Milter is supported by alternatives too
They pretend to, but won't actually run complex milters like
MimeDefang.
Some of the better alternatives don't even _try_ to run milters,
because
they are fully-featured enough in their own right, without needing
to
rely on external software.
Which means that you can't run your choice of tests on a message
during
the smtp conversation before you accept it - at least without starting
a
new process for each one which is expensive for large programs like
spamassassin.
Actually, you don't need milters to do this in postfix (but you can
use milters if you prefer)
If you do it without milters, can you get the efficiency factor that
MimeDefang manages by unpacking the mime parts only once even if you do
multiple scans for spam and viruses? Can it multiplex a small number of
milter backends doing 'slow' steps with a much larger number of mailers
doing fast operations? (MimeDefang may be the only milter designed for
that).
