"Webmaster",
I recently migrated away from Qmail to Exim.
Are you only using Qmail for outbound email? If so you should have zero
problems with dropping Exim in. If you're injecting emails into the
Qmail queue through the qmail "sendmail" binary, you can just replace
that with the exim binary (or a symlink to it) and it will work just
fine.
The Exim config is a single monolithic file, which personally I find
easier to managethan the multiple qmail comfiguration files. The Exim
configure file contains helpful comments :-)
Exim is also a lot faster than qmail at sending out mail from what I can
tell. The log files are also a hell of a lot easier to read.
