Hi list! My postfix used to run together with spamassassin mensioned in master.cf as -o content_filter=spamassassin. I have removed spamassassin because spamc and postfix process cleanup were knocking my server down (swap space at its 80% full). I suspect it is because an aliases miss configuration. Looking at logs , not alway but just sometimes i get this:
Apr 9 22:16:54 mail postfix/error[18713]: 72882266C7: to=<double-
bou...@mailsystem.my>, relay=none, delay=72807,
delays=72805/1.6/0/0.14, dsn=4.3.0, status=deferred (mail transport
unavailable)

Followeb by an another huge ammount of these:
