If you are truly unsatisfied with your current MTA, I'd sugegst that
you at least look at both Exim and Postfix, perhaps testing them on a
testrigg that you feed a copy of your normal mails or similar.
Unsurprisingly, I'd further recommend Postfix for things like sane
config file syntax/ease of configuration, security and to some extent
elegance. In the bargain you get a sometimes less than civil
to-and-fro between Postfix developers and us, but ... that is nothing
to get real excited about. And there might be some jibes/jeering from
certain Sendmail users:-):-).
So far (don't rightly remember how many years:) Jules has provided
excellent Postfix support in MailScanner, and there is not much
speaking for a change in this area.
But I certainly think it best if you form your own opinion by
experimentation/experience:-).
Cheers
