    My mail has been working fine ever since I installed Centos and ISPconfig 3. But today I noticed that all mail to one of my domains gets bounced. I get a message like this one:

    an 19 13:52:06 mydomain postfix/local[24068]: 3AC8B20671: to=<[email protected]>, relay=local, delay=0.04, delays=0.01/0/0/0.02, dsn=5.1.1, status=bounced (unknown user: "vegard")

    I can login to webmail using that user/ e-mail, and I can send e-mail from it.
    The other domains and mailboxes on the same server works fine.

    I must have done something to mess it up, but I can't figure out what!
    I updated ISPconfig yesterday..

    So I checked the maillog again and I saw that I got an error like this:
    "mail postfix/trivial-rewrite[1896]: warning: do not list domain in BOTH mydestination and virtual_mailbox_domains "

    I changed mydestination from:
    mydestination =, localhost, localhost.localdomain
    mydestination = localhost, localhost.localdomain
    in the and then I restared postfix. Now it works.

    Is this because I updated ISPconfig?

    No, ISPConfig doesn't change the mydestination line.
