    Re: Postfix

    So your error logs would suggest your trying to email through google? Have you setup postfix properly to be able to send through google's smtp service? You need to create a one time password to bypass the 2FA on Google to do this and configure postfix to read this one time password within a hashed file.

    I already configured postfix for gmail's two step auth. I followed this site's instructions: https://opensource.com/article/18/8/...transfer-agent

    So what happens when you try to send mail at command line as discussed in the article?

    Re: Postfix

    Just a couple of things, since I walked through this exact same process on my freebsd server like a few months back. Basically encrypted email can be sent over port 587 or port 465. There is a lot of controversy about what port to send encryption over however I'll make a very broad general statement -- both are supported -- 465 was, then it wasn't, and now it is again. Anyway in my experience with gmail -- although I've done it both ways, I've found port 465 to be much more user friendly and prone to less errors.

    I configured my postfix main.cf file a little different than in the source you referenced. I put these lines at the bottom of the main.cf file: (please note that I found this line:
    smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
    totally unnecessary. I don't own this file and I didn't include it.

    Code:
    ## SASL Options
    smtp_sasl_auth_enable = yes
    smtp_sasl_security_options = noanonymous
    smtp_sasl_password_maps = hash:/usr/local/etc/postfix/sasl_passwd
    
    ## TLS Options
    smtp_use_tls = yes
    smtp_tls_security_level = encrypt
    ##Following line required for port 465
    smtp_tls_wrappermode = yes
    tls_random_source = dev:/dev/urandom
    
    ## Relay host
    relayhost = [smtp.gmail.com]:465

    My sasl_password file simply is the following:

    Code:
    smtp.gmail.com  <username>:<two_factor_password>      <------None are in brackets replace the contents including the brackets with the appropriate paramters
    Hopefully that will help. Make sure port 465 is being blocked somewhere.

    Re: Postfix

    I got the same result, so the output said "no mail for rjphares". Here is my main.cf file:

    Code:
    # Global Postfix configuration file. This file lists only a subset
    # of all parameters. For the syntax, and for a complete parameter
    # list, see the postconf(5) manual page (command: "man 5 postconf").
    #
    # For common configuration examples, see BASIC_CONFIGURATION_README
    # and STANDARD_CONFIGURATION_README. To find these documents, use
    # the command "postconf html_directory readme_directory", or go to
    # http://www.postfix.org/BASIC_CONFIGURATION_README.html etc.
    #
    # For best results, change no more than 2-3 parameters at a time,
    # and test if Postfix still works after every change.
    # COMPATIBILITY
    #
    # The compatibility_level determines what default settings Postfix
    # will use for main.cf and master.cf settings. These defaults will
    # change over time.
    #
    # To avoid breaking things, Postfix will use backwards-compatible
    # default settings and log where it uses those old backwards-compatible
    # default settings, until the system administrator has determined
    # if any backwards-compatible default settings need to be made
    # permanent in main.cf or master.cf.
    #
    # When this review is complete, update the compatibility_level setting
    # below as recommended in the RELEASE_NOTES file.
    #
    # The level below is what should be used with new (not upgrade) installs.
    #
    compatibility_level = 2
    # SOFT BOUNCE
    #
    # The soft_bounce parameter provides a limited safety net for
    # testing.  When soft_bounce is enabled, mail will remain queued that
    # would otherwise bounce. This parameter disables locally-generated
    # bounces, and prevents the SMTP server from rejecting mail permanently
    # (by changing 5xx replies into 4xx replies). However, soft_bounce
    # is no cure for address rewriting mistakes or mail routing mistakes.
    #
    #soft_bounce = no
    # LOCAL PATHNAME INFORMATION
    #
    # The queue_directory specifies the location of the Postfix queue.

    #
    #default_privs = nobody
    # INTERNET HOST AND DOMAIN NAMES
    # 
    # The myhostname parameter specifies the internet hostname of this

    # other configuration parameters.
    #
    myhostname = rjphares.localdomain
    #myhostname = virtual.domain.tld
    # The mydomain parameter specifies the local internet domain name.

    mydomain = gmail.com
    # SENDING MAIL
    # 
    # The myorigin parameter specifies the domain that locally-posted
    # mail appears to come from. The default is to append $myhostname,
    # which is fine for small sites.  If you run a domain with multiple
    # machines, you should (1) change this to $mydomain and (2) set up
    # a domain-wide alias database that aliases each user to
    # user@that.users.mailhost.
    #
    # For the sake of consistency between sender and recipient addresses,
    # myorigin also specifies the default domain name that is appended
    # to recipient addresses that have no @domain part.

    # RECEIVING MAIL
    # The inet_interfaces parameter specifies the network interface

    # parameter also controls delivery of mail to user@[ip.address].
    #
    # See also the proxy_interfaces parameter, for network addresses that

    #inet_interfaces = $myhostname, localhost
    # The proxy_interfaces parameter specifies the network interface
    # addresses that this mail system receives mail on by way of a
    # proxy or network address translation unit. This setting extends
    # the address list specified with the inet_interfaces parameter.
    #
    # You must specify your proxy/NAT addresses when your system is a
    # backup MX host for other domains, otherwise mail delivery loops
    # will happen when the primary MX host is down.
    #
    #proxy_interfaces =
    #proxy_interfaces = 1.2.3.4
    # The mydestination parameter specifies the list of domains that this
    # machine considers itself the final destination for.
    #
    # These domains are routed to the delivery agent specified with the
    # local_transport parameter setting. By default, that is the UNIX
    # compatible delivery agent that lookups all recipients in /etc/passwd
    # and /etc/aliases or their equivalent.
    #
    # The default is $myhostname + localhost.$mydomain + localhost.  On
    # a mail domain gateway, you should also include $mydomain.
    #
    # Do not specify the names of virtual domains - those domains are
    # specified elsewhere (see VIRTUAL_README).
    #
    # Do not specify the names of domains that this machine is backup MX

    # the SMTP server, or use permit_mx_backup if you are lazy (see
    # STANDARD_CONFIGURATION_README).
    #

    # to user@[the.net.work.address] of an interface that the mail system
    # receives mail on (see the inet_interfaces parameter).

    # REJECTING MAIL FOR UNKNOWN LOCAL USERS
    #
    # The local_recipient_maps parameter specifies optional lookup tables
    # with all names or addresses of users that are local with respect
    # to $mydestination, $inet_interfaces or $proxy_interfaces.
    #
    # If this parameter is defined, then the SMTP server will reject
    # mail for unknown local users. This parameter is defined by default.
    #
    # To turn off local recipient checking in the SMTP server, specify
    # local_recipient_maps = (i.e. empty).
    #
    # The default setting assumes that you use the default Postfix local
    # delivery agent for local delivery. You need to update the
    # local_recipient_maps setting if:
    #
    # - You define $mydestination domain recipients in files other than
    #   /etc/passwd, /etc/aliases, or the $virtual_alias_maps files.
    #   For example, you define $mydestination domain recipients in    
    #   the $virtual_mailbox_maps files.
    #
    # - You redefine the local delivery agent in master.cf.
    #
    # - You redefine the "local_transport" setting in main.cf.
    #
    # - You use the "luser_relay", "mailbox_transport", or "fallback_transport"

    # the system passwd file in the chroot jail is just not practical.
    #
    # The right-hand side of the lookup tables is conveniently ignored.

    # TRUST AND RELAY CONTROL
    # The mynetworks parameter specifies the list of "trusted" SMTP

    #
    # In particular, "trusted" SMTP clients are allowed to relay mail
    # through Postfix.  See the smtpd_recipient_restrictions parameter

    # clients in the same IP subnetworks as the local machine.

    # with the "ifconfig" command.
    # 
    # Specify "mynetworks_style = class" when Postfix should "trust" SMTP
    # clients in the same IP class A/B/C networks as the local machine.
    # Don't do this with a dialup site - it would cause Postfix to "trust"
    # your entire provider's network.  Instead, specify an explicit

    # The default relay_domains value is $mydestination.
    # 
    # In addition to the above, the Postfix SMTP server by default accepts mail
    # that Postfix is final destination for:
    # - destinations that match $inet_interfaces or $proxy_interfaces,
    # - destinations that match $mydestination

    #
    # In the case of SMTP, specify a domain, host, host:port, [host]:port,

    # ALIAS DATABASE
    #
    # The alias_maps parameter specifies the list of alias databases used
    # by the local delivery agent. The default list is system dependent.
    #
    # On systems with NIS, the default is to search the local alias
    # database, then the NIS alias database. See aliases(5) for syntax
    # details.
    # 
    # If you change the alias database, run "postalias /etc/aliases" (or
    # wherever your system stores the mail alias file), or simply run
    # "newaliases" to build the necessary DBM or DB file.
    #
    # It will take a minute or so before changes become visible.  Use
    # "postfix reload" to eliminate the delay.
    #
    #alias_maps = dbm:/etc/aliases
    alias_maps = hash:/etc/aliases
    #alias_maps = hash:/etc/aliases, nis:mail.aliases
    #alias_maps = netinfo:/aliases
    # The alias_database parameter specifies the alias database(s) that
    # are built with "newaliases" or "sendmail -bi".  This is a separate
    # configuration parameter, because alias_maps (see above) may specify
    # tables that are not necessarily all under control by Postfix.
    #
    #alias_database = dbm:/etc/aliases
    #alias_database = dbm:/etc/mail/aliases
    alias_database = hash:/etc/aliases
    #alias_database = hash:/etc/aliases, hash:/opt/majordomo/aliases
    # ADDRESS EXTENSIONS (e.g., user+foo)
    #
    # The recipient_delimiter parameter specifies the separator between
    # user names and address extensions (user+foo). See canonical(5),
    # local(8), relocated(5) and virtual(5) for the effects this has on
    # aliases, canonical, virtual, relocated and .forward file lookups.
    # Basically, the software tries user+foo and .forward+foo before
    # trying user and .forward.
    #
    #recipient_delimiter = +
    # DELIVERY TO MAILBOX
    #
    # The home_mailbox parameter specifies the optional pathname of a
    # mailbox file relative to a user's home directory. The default
    # mailbox file is /var/spool/mail/user or /var/mail/user.  Specify
    # "Maildir/" for qmail-style delivery (the / is required).
    #
    #home_mailbox = Mailbox
    home_mailbox = Maildir/
     
    # The mail_spool_directory parameter specifies the directory where
    # UNIX-style mailboxes are kept. The default setting depends on the
    # system type.
    #
    #mail_spool_directory = /var/mail
    #mail_spool_directory = /var/spool/mail
    # The mailbox_command parameter specifies the optional external
    # command to use instead of mailbox delivery. The command is run as
    # the recipient with proper HOME, SHELL and LOGNAME environment settings.
    # Exception:  delivery for root is done as $default_user.
    #
    # Other environment variables of interest: USER (recipient username),
    # EXTENSION (address extension), DOMAIN (domain part of address),
    # and LOCAL (the address localpart).
    #
    # Unlike other Postfix configuration parameters, the mailbox_command
    # parameter is not subjected to $parameter substitutions. This is to
    # make it easier to specify shell syntax (see example below).
    #
    # Avoid shell meta characters because they will force Postfix to run
    # an expensive shell process. Procmail alone is expensive enough.
    #
    # IF YOU USE THIS TO DELIVER MAIL SYSTEM-WIDE, YOU MUST SET UP AN
    # ALIAS THAT FORWARDS MAIL FOR ROOT TO A REAL USER.
    #
    #mailbox_command = /usr/bin/procmail
    #mailbox_command = /usr/bin/procmail -a "$EXTENSION"
    # The mailbox_transport specifies the optional transport in master.cf
    # to use after processing aliases and .forward files. This parameter
    # has precedence over the mailbox_command, fallback_transport and
    # luser_relay parameters.
    #
    # Specify a string of the form transport:nexthop, where transport is
    # the name of a mail delivery transport defined in master.cf.  The
    # :nexthop part is optional. For more details see the sample transport
    # configuration file.
    #
    # NOTE: if you use this feature for accounts not in the UNIX password
    # file, then you must update the "local_recipient_maps" setting in
    # the main.cf file, otherwise the SMTP server will reject mail for    
    # non-UNIX accounts with "User unknown in local recipient table".
    #
    # Cyrus IMAP over LMTP. Specify ``lmtpunix      cmd="lmtpd"
    # listen="/var/imap/socket/lmtp" prefork=0'' in cyrus.conf.

    # to use for recipients that are not found in the UNIX passwd database.
    # This parameter has precedence over the luser_relay parameter.
    #
    # Specify a string of the form transport:nexthop, where transport is
    # the name of a mail delivery transport defined in master.cf.  The

    # The luser_relay parameter specifies an optional destination address
    # for unknown recipients.  By default, mail for unknown@$mydestination,
    # unknown@[$inet_interfaces] or unknown@[$proxy_interfaces] is returned
    # as undeliverable.
    #
    # The following expansions are done on luser_relay: $user (recipient
    # username), $shell (recipient shell), $home (recipient home directory),
    # $recipient (full recipient address), $extension (recipient address
    # extension), $domain (recipient domain), $local (entire recipient
    # localpart), $recipient_delimiter. Specify ${name?value} or
    # ${name:value} to expand value only when $name does (does not) exist.
    #
    # luser_relay works only for the default Postfix local delivery agent.
    #
    # NOTE: if you use this feature for accounts not in the UNIX password
    # file, then you must specify "local_recipient_maps =" (i.e. empty) in
    # the main.cf file, otherwise the SMTP server will reject mail for    
    # non-UNIX accounts with "User unknown in local recipient table".

    # JUNK MAIL CONTROLS
    # 
    # The controls listed here are only a very small subset. The file
    # SMTPD_ACCESS_README provides an overview.
    # The header_checks parameter specifies an optional table with patterns
    # that each logical message header is matched against, including
    # headers that span multiple physical lines.
    #
    # By default, these patterns also apply to MIME headers and to the
    # headers of attached messages. With older Postfix versions, MIME and
    # attached message headers were treated as body text.
    #
    # For details, see "man header_checks".
    #
    #header_checks = regexp:/etc/postfix/header_checks
    # FAST ETRN SERVICE
    #
    # Postfix maintains per-destination logfiles with information about
    # deferred mail, so that mail can be flushed quickly with the SMTP
    # "ETRN domain.tld" command, or by executing "sendmail -qRdomain.tld".
    # See the ETRN_README document for a detailed description.
    # 
    # The fast_flush_domains parameter controls what destinations are
    # eligible for this service. By default, they are all domains that
    # this server is willing to relay mail to.
    # 
    #fast_flush_domains = $relay_domains
    # SHOW SOFTWARE VERSION OR NOT
    #
    # The smtpd_banner parameter specifies the text that follows the 220
    # code in the SMTP server's greeting banner. Some people like to see
    # the mail version advertised. By default, Postfix shows no version.
    #
    # You MUST specify $myhostname at the start of the text. That is an
    # RFC requirement. Postfix itself does not care.
    #
    #smtpd_banner = $myhostname ESMTP $mail_name
    #smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)
    smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
    
    # PARALLEL DELIVERY TO THE SAME DESTINATION
    #
    # How many parallel deliveries to the same user or domain? With local
    # delivery, it does not make sense to do massively parallel delivery
    # to the same user, because mailbox updates must happen sequentially,
    # and expensive pipelines in .forward files can cause disasters when
    # too many are run at the same time. With SMTP deliveries, 10
    # simultaneous connections to the same domain could be sufficient to
    # raise eyebrows.
    # 
    # Each message delivery transport has its XXX_destination_concurrency_limit
    # parameter.  The default is $default_destination_concurrency_limit for
    # most delivery transports. For the local delivery agent the default is 2.
    #local_destination_concurrency_limit = 2
    #default_destination_concurrency_limit = 20
    # DEBUGGING CONTROL
    #
    # The debug_peer_level parameter specifies the increment in verbose
    # logging level when an SMTP client or server host name or address
    # matches a pattern in the debug_peer_list parameter.
    #
    #debug_peer_level = 2
    # The debug_peer_list parameter specifies an optional list of domain
    # or network patterns, /file/name patterns or type:name tables. When
    # an SMTP client or server host name or address matches a pattern,

    # debug_peer_level parameter.

    # when a Postfix daemon program is run with the -D option.
    #
    # Use "command .. & sleep 5" so that the debugger can attach before

    I don't understand your main.cf file -- I read it -- Where are all the SASL options as I mentioned above?

    Re: Postfix

    I made the changes to main.cf and sasl_passwd. Still says "no mail for rjphares"
