Laurie,
Everything I know about Exim I weaned from http://www.exim.org. I did buy the O'Reilly book about it, but have found that the web site was easier to get reference material from than the book.
Exim is brilliant at virtual domains, and it takes no effort to convert an existing virtusertable for use with Exim. A domain could even have it's own alias file if you so wish. Lots of configuration options for this sort of thing. Spam support is extremely well support - it supports the RBL and simply telling people to go away is extremely simple.
I would say that you could get a fully working Exim system up and running within 10 minutes. The only gotcha's that I stumbled across were the SMTP AUTH and /etc/shadow support problem and forgetting to specify a UID and GID for piped commands within the alias file.
I am absolutely converted to Exim now. Qmail is also very nice, but for getting something up and running very quickly, I'd always go for Exim.
Regards,
Martyn

How much pain was involved in doing this? I've been running sendmail happily for a couple of years now, but there have been a few vulnerabilities coming along even in 8.12, and maybe it's time to rethink the strategy. I'm about to build/am in the process of building a dedicated email box for our DMZ and now is as good a time as any. Do you have any pointers to how-tos and other stuff for me? Any gotchas?
I do need to be able to handle virtual domains, and I do need to be able to run imap and pop at the same time. Oh yeah, and I need to bounce spam!
Help gratefully received.
Cheers, Laurie.
