I have problems with a recently configured postfix MTA. When postfix starts the following warning appears:

postfix/qmgr[5078]: warning: connect to transport private/filter: No such file or directory

I have amavis-new as a content-filter, but even if I comment-out the relevant line, the warning appears. As a result (I think), of the above, I get errors like below, for every virtual domain that I have:

postfix/error[5080]: 254851834107: to=<info@domainname.com>, relay=none, delay=13082, delays=13082/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)

The good news for me, is that somehow I managed to fix that (don't ask me how!!!!)

The problem is that now I have 50 or so mails, that were affected by the aforementioned problem, in the mail-queue... If I postqueue -f I get the same style of error as before

mail transport
unavailable

However new mails are delivered to their final destination properly...

Any suggestions?

Kind regards.

P.S. Local mail delivery from/to Unix and virtual users, was OK write from the beginning!

That error message indicates postfix is trying to use a transport named "private/filter", which should be defined in master.cf. Do you have a line starting with that in master.cf? If not, you should either add it or change whatever points to it in your main.cf.

Hi, I never had the phrase 'private/filter' or 'filter' in neither master.cf nor main.cf The only close match is content_filter and "smtpd_sasl_path = private/auth" but that have nothing to do... However, I think I fixed it (I changed mydomain and myorigin directives)...but now I have a new problem (see my original post)... –  Sotocan Jan 26 '10 at 16:06

When you get (mail transport unavailable) the real error will be someway further back up the /var/log/maillog. postfix will try a few deliveries and then this error means it knows further attempts will fail so doesn't bother. Try postfix check to see if there are any errors. If you change files in /etc/postfix you may need to you postmap on the file to update it. I was getting SASL auth failed even though I had edited my /etc/postix/sasl_passwd file because I had not run postmap sasl_passwd afterwards to create the sasl_passwd.db file that postfix was actually using for the auth.
