Hi.

I'm pretty new to setting up Postfix/Cyrus, and are currently maintaining a new setup of a mailserver (not my conf.)

We are using Posfix 2.2.10-1 and Cyrus 2.2 and are having problems with mail (randomly) beeing bounced.

Can anyone help me with this?

A example from the mail.log:

Can you for the meantime change the following settings in your /etc/postfix/main.cf to:

mailbox_transport =
mailbox_transport_maps =

fallback_transport =
fallback_transport_maps =

This is how mine is setup by default though I'm using 2.3.4 version currently while yours is still 2.2. Just my idea.

Then reload postfix.

Gani: Dont I need these settings to transport the mail to Cyrus?

I'm not using Cyrus but Courier-IMAP/POP3 and I won't be able to help about this and instead I'm referring you to this guide.

I don't know about Cyrus either, but I use Postfix/Dovecot, and Postfix actually handles the delivery to the mailboxs (in my case Maildir). Dovecot only comes into play once a mail client wants to get mail.

Can you show us the contents of /etc/postfix/transport ?

YES! Dovecot is I'm sure the easiest Mailbox handler to setup than the Cyrus and Courier things. But SQL support is still the one preventing me to use this and specially that it is easier to have an SMTP_Auth by linking Cyrus-SASL to MySQL client library during compile and you can use the same user@domain.com and user-password already in your SQL database for telecommuting users' authentication. This is particulary helpfull for those hosting virtual domains.

billymayday: The only thing in /etc/postfix/transport is the domains we relay to 'own' mailservers (exchange and etc.) ex. domain1.com [smtp:some.Ip.address.com:25]

Questions. Why is your fallback transport the same as normal transport?

Can you post a snip of the log for a mail that doesn't get bounced?
