Mail filtering at server

I'd agree with the learning curve for SA. it's not huge, but there is one.
as for time spend on admin, for me a few minutes per day making sure
there's no new handy handy rules to add by lurking on the sa-users list.
I use RulesDuJour to get most of my non-included rules to update
automatically, and I use MailScanner to glue the MTA, SA and virus scanners
together. Very little work.
But yes for a single user T'birds default spam trap may work quite well and
do the job quickly.
