I have a fair bit of experience with PureMessage... they apparently don't
like sendmail very much (as coders atleast).  my work uses PM and their
support kept telling our mail managers they should consider postfix.  i
cut my teeth on sendmail and told them everything those support people
were telling them was wrong (about sendmail).  out of hte box (using
supplied versions of sendmail and postfix), the PM+postfix was handling
about 700 to 800 messages a  minute on a given test system.  their stock
PM+sendmail only would do about 300 or so per minute.  i screamed
bullchit... about 10 minutes of config tweaking (to their build only, not
recompiling) and it was handling 850 to 950 per minute using sendmail.

that isn't an issue though, i personally don't like PM due to the fact
that it is a serious resource hog.  much worse than any install of MD that
I have used.  2 sun 280r (dual 900mhz proc, 5gig ram, 2x36gig disks)
systems were used as internet facing MX hosts, and both were fairly loaded
all day (all inbound mail for about 20,000 employees, + spam).  we were
rejecting about 300,000 connections per day using the greet_pause alone,
and still getting another 400k to 500k spam messages per day, when they
were using sendmail.  they have sense switched to PM+postfix, so i offer
no advice or help to them anymore (which was one of the things they were
told when they made the decision by my bosses.  they would only get
OS/hardware level support from me).

of the 3 systems (md/canit, brightmail, PM), i personally lean toward
md/canit.  it's by far the most admin friendly, assuming you know wtf you
are doing.  a someone else said lately, it's the swiss army knife in my
tool belt.  all my personal stuff (where i can that is) uses MD...
