Currently my box has postfix 2.1.5 installed. But I
see that I can
install one of the following:
Exim 4.50 (stable)
Exim 4.52 (testing)
Postfix 2.2.4 (testing)
Lots of people here are very familiar with Exim. The biggest gotcha with it
is Debian packages it in many little config-file-lets, which are combined at
config reload into a single file. I like it that way, others not so much.
I'd run Exim 4.5 out of those choices. 3.x is deprecated and 4.5 is
certainly up to date.
I know Daniel is fairly familiar with Exim but I know
these alternative MTAs. Can anyone provide sage advice on which has
more features, is easier to configure, has powerful plugins, db
support, IMAP server integration, virtual domains, spam filtering
that sort of thing.
Spam/virus filtering is done by 'exiscan', which is included with exim as of
4.5. Everything else is just there.
Are you familiar with sendmail? Is there any reason you don't want to keep
