Virtual Mail Server

Hi folks. Looking to set up a UNIX virtualized mail server. One IP
multihosting domains with POP3 and SMTP access. Would have to use an
alternative authentication database other than the normal UNIX entries
(NIS, /etc/passwd, etc.). Basically, looking for as much information as
possible; code patches would be nice to review-- what ingredients you
mixed (ie, eric's sendmail, cucipop, and procmail, or whatever) would
still be appreciated a lot. Basically, if you've done this or know who
has, this would help me a lot from re-inventing the wheel here.

Thanks!
--Nathan.

For starters, see <http://www.sendmail.org/virtual-hosting.html>.


You might also be able to hire a consultant from Sendmail, Inc. to help you with this.  See <http://www.sendmail.com/> or send e-mail to "info@sendmail.com".

Alternatively, post another note here (which I'll be notified of) that you want me to contact you directly by email, and I'll do so.

Nope. This isn't enough. The user must not have to be in the /etc/passwd or the NIS maps on the server. You should also be able to have usera@domain1.com and usera@domain2.com without having to remap usernames to avoid the problems of the same name. And consulting isn't an option, either, that's what they pay me for. =) Just trying to find more information or see if someone has already implemented this. I need independant authentication of usernames, some password file per domain storing information with a separate spool directory per domain avoiding username overlaps. This also allows us to quota the domains as a whole and not individual users. Make sense?

Look, I've done this sort of thing at GNN (Global Network Navigator, a joint venture between O'Reilly & Assoc. and America Online, back before AOL killed it), and I've consulted with some of the world's largest "freemail" service providers on solving precisely this problem, amongst others.

If you won't believe me, or can't accept the answers I gave you by email, then so be it -- go ahead and reinvent the wheel, please.  I'm sure everyone in the industry would benefit by the application of your omniscience on this subject.

For some reason this system duplicated my rejection on the "For Starters" (*blinks at Expert's CGI system*). Thanks for the email, I dropped a reply. I think that when I hit reload to check if someone had updated this page, it probably reposted what I'd done last time. They might want to look into that... =)

Ahh, okay.  I was really beginning to wonder about that.


Anyway, sorry if I came off rude.  It's been one of those days, and you were unfortunate enough to catch that.
