Message  filtering  and  delivery  have  ALWAYS been paired within the
IMail process flow. I don't think you've been polite enough to deserve
an  explanation of the similarities in implementation across versions,
but  if  you  do  your  due  diligence  in  this  area  perhaps you'll
understand it better.

> Name some other mail servers that you know combine these processes.

This  isn't  about  other  mail servers. It's about the evolution of a
product  from version to version while preserving central paradigms in
order  to  avoid  needless  ground-up rewrites. In terms of other mail
servers,  unless  you're  doing streaming content filtering during the
SMTP  conversation (which would be resource suicide), you've signed on
to  doing  post-submission  filtering,  then  delivery. Whether or not
other  mail servers have separate filtering and delivery stages, IMail
has   historically   only   had   the   submission   stage   and   the
filtering/delivery stage, and that it is why it comes as absolutely no
surprise  that  QM  is  an high-performance implementation of the same
paired functions.

> How is it that you can speak so authoritatively about this subject?

It  is  so  because  I know how IMail's process flow has worked in the
past  and  how  it  has evolved. I have no professional alignment with
Ipswitch,  although  I  have  been  part of the requirements gathering
process as a beta tester for several versions.
