[NTLUG:Discuss] Virtual Mail Users

[David Camm]

i've dumped sendmail, etc along time ago in favor of surgemail (see 
www.netwinsite.com) which provides smtp, pop and impa support.

surgemail allows many authentication methods aside from unix accounts.

i'm not sure about cyrus, but i would bet if you asked nicely they'd do that for 
you. their authent process has an open api, so you could even do it yourself.

if you've written scripts executing the sendmail binary, they have a replacement 
which will function transparently.

too many other great things to mention (web interface, spam filtering, friends 
lists, plugin virus scanning). it's GREAT software. and very cheap (altho not free).

check them out.....
