That is only a relatively rare problem when using a milter with
postfix (possibly only with Postfix 2.4), so isn't really a common
problem... Hence I will do something about it tomorrow or Tuesday, not
a few minutes ago;-)

Mostly "politics", that has very little bearing on anything. They've
been unhappy with us for years, and it has mostly just been working
(at least as well as any of the other supported MTAs) for the same
The latest quirk from Wietse just need some fine tuning, and then all
is back to normal;).

Depending on your view of things you will get "yes, use my pet...",
"no, postfix rulez...." and "not really.... and not any worse
either... It all depends...":-). If you pressed me for a
recommendation I'd give you number three;-)

If you don't know your MTA, when it is so relatively easy to work
with... Well, lets just say you need read up on any MTA you finally
decide to use, including Postfix:-D.
There is quite a lot of stuff written on the MailScanner wiki about
tricks and tweaks and setup recommendations for most MTAs in general,
but perhaps most specifically for Postfix... One could interpret that
as postfix being difficult (if one were an Evil Bunny, like Res:), or
as a testament on the configurability of the combination.

Sendmail probably gets the most thorough rundown, since a) there are
more sendmails out there, and b) Jules favours Sendmail.
Exim and Postfix are pretty close in support (to sendmail), while
Zmail and Qmail are less well covered (even though the Evil Bunny
works on the Qmail port, and Leonardo Hellman seems to keep the Zmail
one alive,from time to time).

Although the solution will look different for all MTAs, they can all

No problem for any of them.

If you are at all familiar with the Postfix you use already, stick
with it. If you want a slick package based on Sendmail, buy DefenderMX
(commercial MailScanner+MailWatch and a tad more) from Fortress
