Mail problems after following Virtual Users And Domains With Postfix, Courier

    I followed the instructions on "Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1)" and everything is running but I can't get outlook to sync with the server because of some permission or file creation problem. the smtp server seems to be working as i do smtp.mydomain.com and a test email can be sent through and the login is accepted.

    However the pop3 server is not responding. Is pop3.mydomain.com suppose to be the pop server or is it suppose to something else?

    Jan 6 21:55:28 localhost pop3d: Connection, ip=[::ffff:210.193.49.322]
    Jan 6 21:56:13 localhost pop3d: chdir mydomain.com/mydomain_director/: No such file or directory
    Jan 6 21:56:30 localhost pop3d: Connection, ip=[::ffff:210.193.49.322]
    Jan 6 21:56:48 localhost pop3d: LOGIN FAILED, user=mydomain_mailer, ip=[::ffff:210.193.49.322]
    tail: cannot open `error' for reading: No such file or directory


    i seem to have be able to send a test message

    One extra question, how do i stop an account from receiving email but allow it to send email? this is for a user authentication system.
    this is the mail log error. apparently there are no directories created for the users

    Are you sure you have given permissions to the /home/vmail directory as per the howto?

    As for an e-mail addy that can send but not receive you just send with a from addy that doesn't exist. Something like [email protected]. The mail server doesn't need to know about it at all. However if you need to authenticate against your SMTP server in order to send that then you will need to provide your script with credentials (any will do, you don't need to setup an specifically for it).

    hmm i think the second question should be in another thread. don't want to get the two mixed up.(btw i still don't get what u mean but never mind i'll start another thread on it)

    Back to the important thing yes i did try this:

    groupadd -g 5000 vmail
    useradd -g vmail -u 5000 vmail -d /home/vmail -m

    which gives me back

    [root@localhost ~]# groupadd -g 5000 vmail
    groupadd: group vmail exists
    You have new mail in /var/spool/mail/root

    [root@localhost ~]# useradd -g vmail -u 5000 vmail -d /home/vmail -m
    useradd: user vmail exists


    is there something i have missed?

    Well that creates the user and group on the system. So that's a good start.

    What are the permissions on the /home/vmail directory? Who owns it?

    'ls -la /home'

    Would spit out what we need to see.

    drwx------ 3 vmail vmail 4096 Jan 6 13:19 vmail

    And the contents of the vmail directory. Does it have the same perms/ownership?

    hrm...interesting.

    Looks like postfix isn't creating the domain/user directories. Did you send a test message TO an account in your domain? IE send a message to [email protected] and make sure your server logs show it was received and sorted by your mail server. Then check the /home/vmail dir again to see if a directory "yourdomain.com" was created with a user directory under it called "you" (based on my example above).

    And your logs show that the message was received by your server and delivered to a mailbox?

    tail -f /var/log/mail.log

    uh oh i am gussing a bad mx record inc
     
  15. volksman

    volksman New Member

    Yup...although it may not be an mx record. Your host just can't find an IP for mail.mydomain.com. Can add that to /etc/hosts for testing or get your DNS server to properly announce the IP.

    Funny u should say that i don't really know much about changing the host file or dns. where would i add it?

    there is only 1 ip currently for the server

    /etc/hosts

    # that require network functionality will fail.

    That zone looks ok. From your server can you resolve mail.mydomain.com:

    dig +short @localhost mail.mydomain.com

    If you get an IP back from that command then the DNS is setup correctly and you may just need to update /etc/resolv.conf to use localhost for lookups and not a third party server.

    If you don't then you have DNS issues too.

    /etc/hosts would look something like:

    xxx.xxx.xxx.xxx mail.mydomain.com

    save and exit and your machine should resolve mail.mydomain.com.

    dig +short @localhost mail.mydomain.com

    does not give anything in return.
     
  19. volksman

    volksman New Member

    Then your DNS is busted too. So update your hosts file for now to test the mail server. Once you get that working then focus on cleaning up the DNS issue.

    When i update the host file do i need to restart any services?
