As others already said, there is no 'Host: ' like in HTTP/1.x so users have to put their entire mail address as a login. The Vhffs subsystem (Virtual Hosting For Free Software, used on TuxFamily.org, a free software hosting service) uses exim + courier + mysql for providing multidomain pop/imap/webmail (ssl or not) without filling the passwd file with crap :) You can just get the packages as examples (Vhffs is actually at a experimental devel stage...) at: deb ftp://ftp.vhffs.org/debian vhffs main deb-src ftp://ftp.vhffs.org/debian vhffs main I appreciate any help you may provide, Appreciating any feedback...

RE: Virtual Hosting for Email
Thanks for the replies Jeremy... Well thats what I was looking for, and I figured that about the POP3 (kind of a shame, isnt it :P). I think ill go with using the full emails for their logins. but i dont want to use the linux auth for pop/imap/mta. Im expecting to have several hundred email addresses with only a few (10-20) for ssh. Id rather not fill my passwd file with junk. Is this possible? =) The other tech in my office managed to get exim/cyrus to read another file passwords (which i could probably replicate) but we still had to add the user to linux (just adduser --system --disabled-password userand authenticate with a htpasswd file).

I dont even want shell access for each user, so another Like the other poster said, this is not possible, and you need your users to specify their entire e-mail address. I'm currently setting something like this up for my own company, and basing it on Courier (www.courier-mta.org). I have the following setup: - Completely virtual accounts for all users (so no accounts for mail users in the regular password file, only in a mail-users-file) - Virtual domains, each their own users/passwords etc - Account info stored in mysql/postgres/gdb-file or textfile - Imap/Pop/Webmail based on the same system with virtual accounts - Support for SSL/TLS in all subsystems (POP3S/IMAPS/Webmail-ssl, esmtp-tls) Setup was quite doable with the on-line documentation and some googling Using the virtual accounts also makes sure the users can never login using ftp/ssh/telnet/whatever, only for pop3/imap/esmtp/webmail (and you can give them separate passwords for each if you want, so when you only give them a pop password they cant use webmail and vice-versa) method of authentication would be best anyways. I have attempted to find some documentation on this, (and Im sure I'll get a lecture for this ;) but I havent found anything that explains it well. 1) Im wondering if this is possible, or what is the next-best solution. 2) Im looking for documentation on this that explains WHY you follow the steps you do, not just how to do it.
