    POSTFIX SMTP Help

    Hi All,

    I have setup POSTFIX on our server and can receive email and pop3 into it to grab mail. So far so good. However I cannot connect a mail client to send mail via smtp through the server itself.

    I have followed the articles at:

    https://help.ubuntu.com/community/Po...asicSetupHowto
    https://help.ubuntu.com/community/Postfix

    I keep receiving the following message

    Server response: 535 5.7.8 Error: authentication failed: generic failure code(535)

    Here is my configuration for /etc/postfix/main.cf (removed domain info)

    Code:
    # See /usr/share/postfix/main.cf.dist for a commented, more complete version
    
    
    
    # Debian specific:  Specifying a file name will cause the first
    # line of that file to be used as the name.  The Debian default
    # is /etc/mailname.
    #myorigin = /etc/mailname
    
    
    smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
    biff = no
    
    
    # appending .domain is the MUA's job.
    append_dot_mydomain = no
    
    
    # Uncomment the next line to generate "delayed mail" warnings
    #delay_warning_time = 4h
    
    
    readme_directory = no
    
    
    # TLS parameters
    smtpd_tls_cert_file = /etc/ssl/certs/smtpd.crt
    smtpd_tls_key_file = /etc/ssl/private/smtpd.key
    smtpd_use_tls=yes
    smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
    smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
    
    
    # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
    # information on enabling SSL in the smtp client.
    
    
    myhostname = mydomain.com
    alias_maps = hash:/etc/aliases
    alias_database = hash:/etc/aliases
    myorigin = /etc/mailname
    mydestination = mydomain.com, localhost.mydomain.com, localhost, mail.mydomain.com
    relayhost = 
    mynetworks = 127.0.0.0/8
    mailbox_size_limit = 0
    recipient_delimiter = +
    inet_interfaces = all
    inet_protocols = all
    home_mailbox = Maildir/
    mailbox_command = 
    smtpd_sasl_local_domain = 
    smtpd_sasl_auth_enable = yes
    smtpd_sasl_security_options = noanonymous
    broken_sasl_auth_clients = yes
    smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
    smtp_tls_security_level = may
    smtpd_tls_security_level = may
    smtpd_tls_auth_only = no
    smtp_tls_note_starttls_offer = yes
    smtpd_tls_CAfile = /etc/ssl/certs/cacert.pem
    smtpd_tls_loglevel = 1
    smtpd_tls_received_header = yes
    smtpd_tls_session_cache_timeout = 3600s
    tls_random_source = dev:/dev/urandom
    smtpd_sasl_type = cyrus
    cyrus_sasl_config_path = /etc/postfix/sasl
    Any help appreciated
