I'm aiming at RPM. RedHat used to use Sendmail; I think Debian uses
Exim but uses apt. Don't know about Suse.

My main point though was that all of them had reasons to dump
Sendmail.

Thanks for the informative post Gonzalo.

I like the look of the Dragonfly approach (although I don't use it).

Perhaps in FreeBSD 10* somebody might work to incorporate one or the
other (DMA or OpenSMTP) and strip out Sendmail and leave it in ports
where it belongs.

I can see that having real benefits in licensing, footprint and
usability.
