Greetings -
I'm "experiencing" vpopmail and it seemed like a good idea to organize my
thoughts on how vpopmail delivery is controlled. So I constructed the
following, sort of a mini-FAQ. I haven't tested these (yet), just cribbed
them from various web resources. Any critique of this would be useful to me
(and others, I hope).

Controlling virtual domain delivery with qmail + vpopmail
-
You can use .qmail files to control incoming email delivery at various
degrees of fineness. To become familiar with the five types of delivery
instructions that can appear in a .qmail file, see man dot-qmail (available
online at http://www.qmail.org/man/man9/dot-qmail.html).
There are two places to put the .qmail files (using the fictitious domain
"yourdomain.com" and user "someuser"). The .qmail files can be placed at
the per-domain level
/home/vpopmail/domains/yourdomain.com/.qmail-extension
or at the per-user level
/home/vpopmail/domains/yourdomain.com/someuser/.qmail
Here's a look at the various types of delivery that you may want to use...
SENDMAIL-like ALIAS
---
You want to accept and forward mail for a user ("otheruser") who does not
have a mailbox on your local system. Put:
[EMAIL PROTECTED]
in a .qmail file at the domain level with a -extension of the name given to
the user who does not have the mailbox:
/home/vpopmail/domains/yourdomain.com/.qmail-otheruser
SIMPLE FORWARDING of a REAL USER
A real user could be forwarded in the same fashion as the SENDMAIL-like
ALIAS above, but you can wind up with serious pollution of the domain-level
directory with all those .qmail-someone files. A more manageable solution
might be to put:
[EMAIL PROTECTED]
in a .qmail file at the user level. This file has no -extension since the
user is unambiguously identified by the directory.
/home/vpopmail/domains/yourdomain.com/someuser/.qmail
FORWARDING ALL MAIL for ONE DOMAIN to a DIFFERENT DOMAIN
Let's first assume that you have no users in the current domain (why else
would you be forwarding all their mail elsewhere?). Put:
| /home/vpopmail/bin/vdelivermail '' $[EMAIL PROTECTED]
in the .qmail-default file at the domain level:
/home/vpopmail/domains/yourdomain.com/.qmail-default
This will forward all non-matching emails to user@newdomain.com
DELIVERING a MESSAGE to TWO (or MORE) USERS
---
Say that you want to deliver incoming messages for "someuser" to that user
and also to "someotheruser". Construct a file that contains
./someuser/Maildir/
./someotheruser/Maildir/
or
./someuser/Maildir/
[EMAIL PROTECTED]
and place them in a .qmail file at the domain level
/home/vpopmail/domains/yourdomain.com/.qmail-someuser
DELIVERING a MESSAGE to TWO (or MORE) USERS, PART DEUX
--
Say that you want to deliver incoming messages for a user, "someuser", who
may or may not exist on the local system, to two existing users neither
one of whom is someuser. Construct a file that contains
./realuser1/Maildir/
./realuser2/Maildir/
or
./realuser1/Maildir/
[EMAIL PROTECTED]
or
[EMAIL PROTECTED]
[EMAIL PROTECTED]
and place them in a .qmail file at the domain level
/home/vpopmail/domains/yourdomain.com/.qmail-someuser
The originally addressee never receives the mail because there is no
delivery instruction for "someuser" and, therefore, doesn't have to exist.
DELIVERING a MESSAGE to TWO (or MORE) USERS, PART TROIS
---
Another way to deliver incoming messages for "someuser" to that user and
also to "someotheruser" but preventing pollution of the domain-level
directory... Put:
./Maildir/
[EMAIL PROTECTED]
in a .qmail file at the user level
/home/vpopmail/domains/yourdomain.com/someuser/.qmail
This makes most sense when someotheruser is not in the local domain. But it
should work even if someotheruser is local. Of course, the original
addressee must have a mailbox on the local system.
HANDLING MAIL THAT DOESN'T MATCH ANY USER or .QMAIL FILE
Mail that doesn't match any user or .qmail file is handled according to the
contents of the .qmail-default file on a per domain basis. Find this file at:
/home/vpopmail/domains/yourdomain.com/.qmail-default
If you want to bounce undeliverable mail, that file should contain:
| /home/vpopmail/bin/vdelivermail '' bounce-no-mailbox
If you want to send undeliverable mail to a given user, make it say:
| /home/vpopmail/bin/vdelivermail '' [EMAIL PROTECTED]
