Howto: set up a mail server in Ubuntu

[forsakenrider]

This seems like the best tutorial on the net! I've been pulling my hair out for days though. Took me forever to figure out my ISP blocks port 25!

I have a service with my dynamic DNS provider that should solve just this problem, an e-mail port forwarder. I can use a different port like 2525 or 26. Im not sure how to implement this with postfix. I have tried "relayhost = waterlowphotography.com:2525" But it doesnt seem to work. Does anyone know what I should do? I have started my install fresh and am now at the first "test" point after a simple server install.

try to forward port at your router - outside 2526 WAN : inside (LAN) 25

I edited the configuration files restart postfix and this is what i get

Feb 09 15:26:01 linux-clui.site postfix/sendmail[30911]: fatal: chdir /var/spool/postfix : No such file or directory

but that directory exists maybe some permission issue?

ls -la /var/spool/postfix

/var/spool/postfix:

and the only variable with that value is : queue directory so it should be fine, or could it be some permission issue?

actually it was problem that I've commnet on that line, delete command and it restarted like breeze, little weird. though..

so running as expected

telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

but no output telnet hangs here

I need help everything works flawlessly apart from being able to sent email from a mail client i get relay access denied, the only way i can get it to work is if i add my ip or and external ip (if i want to access from another location), to the mynetworks in postfix/main.cf
I started another thread before i realised this one existed. http://ubuntuforums.org/showthread.p...7#post12924217

once everything is up and running smooth i will donate for your fabulous tutorial flurdy

My configs are posted in the other thread as well as the error message.

Hi,

i've just followed this freaking awesome HowTo http://flurdy.com/docs/postfix/ and everything is working fine for the last six weeks but i also realized everyone can send emails through telnet on port 25 without the need of authenticating. Could someone explain me if that's been made on purpose?

Thanks a lot mates!

[roberto32]

also solved that but another problem comes at the mysql - postfix "binding",

/etc/postfix/mysql_mailbox.cf

is this

user=mail 
password=mailPASSWORD 
dbname=maildb 
table=users 
select_field=maildir 
where_field=id 
hosts=127.0.0.1 
additional_conditions = and enabled = 1

, so that looks like every will have same password.....???

and what's that filed crypt in users table for? like sholdn't it bee like that

 AES_ENCRYPT('password_for_particular-user',SHA2('mailPASSWORD',512))

so that mailPASSWORD is meant like encryption key ?

just a note for the people who are adding roundcube this will save you a small headache.
if roundcube cant send an email you need to do this.

Adding User Accounts

Note: If you set $rcmail_config['smtp_user'] and $rcmail_config['smtp_pass'] to '%u' and '%p' respectively in config/main.inc.php, you do not have to do the following steps.
Unfortunately, due to how Dreamhost has its email account system set up, RoundCube will not work out-of-the-box as it usually does. We have to manually add any accounts we want to be able to log in with to the users table in our MySQL database. Hopefully, an Admin interface that makes this easier will be added in the future. Until then, we get to do it the old-fashioned way.

1. Log into your database via phpMyAdmin (http://rcdb.yourdomain.com in our installation example).
2. Click on the link to the users table in the left frame after you've selected your database from the dropdown menu.
3. Click on the "Insert" link at the top of the right frame.
4. The only fields you need to enter information in are username, mail_host, and alias. Username is user@domain.com (the same username this user would use for a normal email client), mail_host is mail.yourdomain.com, and alias is whatever you want the user to enter in the username field when logging into RoundCube.
5. Hit the Go button at the bottom of the page to submit the form after you've supplied the correct information.
6. Repeat for each user you want to have access to your RoundCube installation.
7. Log into RoundCube and add the following folders on the options page.
   
   • Drafts
   • Sent
   • Junk
   • Trash
   
   
8. To activate mail sending, you will also need to create an identity under Personal Settings --> Identities.

if roundcube cant log into the server you need to make these changes

$rcmail_config['imap_auth_type'] = LOGIN;
$rcmail_config['smtp_server'] = 'ssl://localhost';
$rcmail_config['default_host'] = 'ssl://localhost:993';
