IMail    was   certainly   originally   designed   for   single-server
environments.  Remarkably,  plenty  of  servers  running IMail 7.x and
earlier are still in use as both MXs and mailbox servers, though queue
management  prior  to 8.x is certainly not up to snuff.

The  concept  of "efficiency" is site-specific, and many admins forget
that  there  are  sites that see just a few thousand messages per day,
shifting  the question from "Can my software/hardware combo handle the
overall  traffic  level, including legit and illegit mail?" to "Can my
software/hardware  combo  efficiently filter spam and viruses with the
highest  administrative  comfort  level,  lowest  ruleset  maintenance
requirements,  and  user  self-management  features?" You can't simply
think   of  PostFix/SpamAssassin  as  the  "free"  version  of  IMail,
IMail/Declude, or IMail/mxGuard. There's a lot more to know.
