Slow mail delivery when Spamassassin is enabled

[thewolf]

Hi,

We're running Plesk 7.5.4 with all the latest hotfixes on Red Hat Enterprise Linux 4 Update 5.

We've noticed that after enabling Spamassassin ("Server wide settings" mode, we're not interested in "Personal settings" mode for now) mail delivery gets slower, e.g. even sending a test message to self will take about 30 seconds or so before it gets in the mailbox. If we disable Spamassassin mail delivery get's back to normal, that is almost immediate.

Also, when Spamassassin is enabled, we've noticed a lot of error messages in the /usr/local/psa/admin/var/log/maillog file, see below.

Please advice on how to speed up mail delivery with Spamassassin enabled and how to prevent the error messages in the log file.

Thanks.
