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=, 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!
