Broken Fetchmail/Postfix - recipient not found
 

Hi Guys,

I have previously posted this under "General" but thought that this would be a better forum suited to my question...

I have obviously done something to my mail system that I just about managed to get set up several months ago... still not quite sure what I have done. When I try to get mail using fetchmail I get this output:

====
fetchmail: SMTP> RCPT TO:<steve@localhost>
fetchmail: SMTP< 450 <steve@localhost>: Recipient address rejected: User unknown in local recipient table
fetchmail: SMTP error: 450 <steve@localhost>: Recipient address rejected: User unknown in local recipient table
fetchmail: SMTP> RSET
fetchmail: SMTP< 250 Ok
...... not flushed
====

exceprt from output of fetchmail -v -f /etc/.fetchmailrc

When I try to send a test mail to my steve@localhost using a mail client on a windows machine I get the error saying that this address could not be resolved, neither can root, postmaster or any other "valid" local address.

I can access the IMAP mailboxes without problem, and have obviously checked that the steve account exists in /etc/passwd

I really am not sure what I have broken. IIRC it is a Cyrus IMAPd mailbox, with Fetchmail > Postfix. All mail downloaded with fetchmail is set "is steve here"

My /etc/postfix/main.cf

Can anybody suggest what to look at next? I have already tried googling the SMTP: error 450, it would seem only to return results on the subject of rejecting unknown inbound e-mail rather than resolving this... unless I have missed something!

Thanks,
Steve Williams

Hi Guys,

Thanks to everyone that read this thread... I have now resolved the problem, for anybody in the future experiencing similar problems, if you try looking at your /var/log/mail/warnings file, you may find that the mail system is having trouble accessing the user database. This is caused by broken permissions on your /etc/passwd file, I have set mine to CHMOD 744 and this solved the problem.

Thanks again for your time in reading this thread.
