Hi,

I'm setting up a mailserver for one domain with Postfix+Cyrus-imapd+cyrus-sasld… This is on CentOS4 (RHEL). I'm pretty sure I got postfix working OK… I can use the mail command to send a test message to an external account an it works fine. When I try to send mail to a local user, though, I get a message like this:

Mar 30 09:42:16 li9-32 postfix/pipe[28596]: 33CD441BA6: to=<sam@predisposition.com>, relay=cyrus, delay=1001, status=deferred (temporary failure. Command output: couldn't connect to lmtpd: Bad file descriptor_ 421 4.3.0 deliver: couldn't connect to lmtpd_ )</sam@predisposition.com> 

predisposition.com is the domain for this server. I have tried changing the mailboxtransport in /etc/postfix/main.cf a couple of times – the above error comes after changing mailboxtransport to "cyrus"… I get a similar error if I change it to either of the following:

#mailbox_transport = lmtp:unix:/usr/lib/cyrus-imapd/lmtpd

Mar 30 09:55:37 li9-32 postfix/lmtp[28644]: 7D85641BD7: to=<sam@predisposition.com>, relay=none, delay=0, status=deferred (connect to /usr/lib/cyrus-imapd/lmtpd[/usr/lib/cyrus-imapd/lmtpd]: Connection refused)</sam@predisposition.com> 

mailbox_transport = lmtp:unix:/usr/libexec/postfix/lmtp

Mar 30 09:54:18 li9-32 postfix/lmtp[28626]: 71D5641BD4: to=<sam@predisposition.com>, relay=none, delay=1100, status=deferred (connect to /usr/libexec/postfix/lmtp[/usr/libexec/postfix/lmtp]: Connection refused)</sam@predisposition.com> 

I've searched through many tutorials and find it's hard to get a coherent idea of how to set this up – any help would be MUCH appreciated.

Thanks,

Sam
