Postfix serves for my virtual domains and works fine. But for one of my domains: - it bounces mails targeted at [email protected] - it rejects mails targeted at [email protected]

problem is, [email protected] does not exist either.

here is my postconf

why does it bounce [email protected], and reject other non existing mails?

Thanks.

It's hard to tell without seeing a bounce message. Check the bounce error message and also look into your mail log (frequently /var/log/mail.log or maillog) to get more information about why it is bouncing.

Edit: OP solved problem by removing unix:passwd.byname from local_recipient_maps in the main.cf Postfix configuration file.

  • argh! seems that postfix accepts the mails for [email protected], then finds out that no systemuser mailbox exists for virtualdomain.tld and bounces.. i've tried it with system(linux) users such as mail, news, games @virtualdomain.tlds i'm hosting and all bounced. but bogus account names such as foo, bar etc. are rejected.

  • well, you can remove the system users as valid users from your postfix configuration, if no local (/etc/passwd) users are meant to get mail. i don't know off the top of my head how to remove the configuration, but it shouldn't be hard. i presume you're using virtual users hosted in a database or something?
