I think this part of question was referring only to MTAs, not MTA +
anti-spam/virus tools. Anti-spam tuning is really a bit slower to do than
general performance tuning (MTA or MTA + anti-virus), but this will be true
to whatever MTA software and anti-spam one might buy.

Outsourcing is usually a good way to get a solution with expertise instead
of a next->next->finish software installation and license to use it... but
for ISP use, integration with internal OSS (billing, tech-support etc.)
seems to be a challenge. Outsourcing costs also keeps most ISPs from using
such a solution, unless time-to-market is the one and only criteria.
