Re: Sendmail Question- want username@yourdomain.com as login?

[Al Sparks <data345 yahoo com>]

Well, qmail and sendmail, as do most mail transport agents (MTA) have
one thing in common.  They actually don't do password authentication.
They just deliver mail.

Now, unlike sendmail, qmail does come with a POP3 package installed, and
that's presumably because qmail's default install settings use Maildir
format instead of mbox format.  (To summarize: mbox format is where each 
user's mailbox consists of 1 file with more than one message usually located
in /var/spool/mail, whreas Maildir format uses separate files for each mail 
message, usually located in $HOME/Maildir).

So, if you're going to investigate qmail for this functionality I'd look at
qmail-pop3 (and if you plan on using that, make sure you use Maildir format)
and also investigate Boorstein's checkpassword program (Boorstein created
and maintain's qmail).  Perhaps that uses the username domain com format.

I can't help you much with that, because I provide IMAP to access the qmail
accounts I administer, specifically courier IMAP.

Regarding virtual accounts, I googled qmail's docs real quick, and didn't 
find anything.  Perhaps you're referring to virtual DOMAINS.  All a virtual
domain does is tell the MTA to accept email addressed to
   "username sedonddomain com"
whereas without that spec, the MTA will either bounce the message or attempt to 
relay it.

Another feature qmail has (and you can also configure sendmail to do the same
thing) is the abiity to set up more than one mailbox for one account.

The way it works is, given an account, "userid", you can configure that acount
to deliver email to another mailbox if you email to "userid-blah domain com".
