Sure you're not swapping? Taking an hour to process a message sounds like
the box is getting out of memory.
Regardless, you want a dedicated mail server if you get any significant
mail volume. For higher volumes spamassassin really needs it's own box.
Some suggestions:
- Use "clamd" and "clamdscan" instead of the commandline clamscan.
- Lower the maxproc setting for the filter process in Postfix master.cf
- If your filter script writes to a temp file, try to rewrite it so
everything is done through pipes.
- To reduce the perl's startup overhead, try compiling sanitizer.pl using
"perlcc" (may not work depending on your perl). Persistent Perl
(http://daemoninc.com/PersistentPerl/) may also work.
