but over what period? need to calculate a "msgs per time", no?
One LSMTP user told me that with 200 SMTP client processes sqawned (the max
process number is an LSMTP license restriction), the Solaris machine was
delivering an average of one 1 msg every 7 seconds, for I think 20 or 30
thousand msgs, IIRC. This of course isn't screamingly fast delivery and
obviously the SMTP protocol handshaking and slowness-over-Internet of the
SMTP client (LSMTP) to remote SMTP server would be the dominating factor
for sending.
In the discussions I've seen with Wietse Venema in the postfix.org user's
list, the postfix developer, he says the limiting factor is the disk
channel, and more specifically, the mechanical delays of head movement time
an disk rotation time (as opposed to delivered bit rate once on track)
since the RFC requires that every incoming msg be committed to disk before
the SMTP server sends RECD back to the SMTP client.

For incoming mail and anti-spam defenses, does the iMS SMTP server do
lookups to Mail-Abuse.org, or reverse the SMTP client ip for validity? or
validate that the SMTP client has MX and A records? These are growingly
common anti-spam techniques for mail servers sticking their faces right
into the Internet nastiness.
btw, Howie, for a candidate "iMS mail application", take a look at
www.Mustang.com's own "IMS", vbg.
This product is considered to have pride of place in its category and I
think that the category would it would be an ideal target for an "iMS"
application.
