ASSP, Declude, Sniffer, Imail anti-spam/virus all require
additional, significant processing on the mailbox server.
The point is the two-box solution, whatever the software.
Not neccesarily. The ASSP solution on the same box will drasticly
reduce the amount of mail received and passed on for AV testing and
mail delivery.
but all the work to reduce the mail is done on the mailbox server,
and that work is very expensive. Of course if you have a low-volume
of message and 3+ GHz, 2 GB RAM, and 15K RPM SCSI to handle it, you
can do everything on the mailbox server.
Does ASSP answer on port 25? Does ASSP reject unknown recipients? If
Imail answers on port 25, I know from many experiences that Imail is
very rapidly bogged down simply refusing unknown recipients, a job
that is best done by a second, upstream box.
If you have small volumes and small abuse problems, one (powerful)
box works fine, but it doesn't scale well.
