OK.. How about this example.
1) You have an alias /var/qmail/alias/.qmail-ppp (in this file you have
&[EMAIL PROTECTED]).
2) You also have an alias /var/qmail/alias/.qmail-pppindia (in this file you
have [EMAIL PROTECTED]).
3) you have /home/ksamy/ as your real account.
An email is sent to [EMAIL PROTECTED]
The mail gets delivered to ppp (then the Delivered-To: ppp header is added).
qmail then sends this to [EMAIL PROTECTED]).
When the mail gets to pppindia another Delivered-To header is added (because
it was delivered to pppindia).
Then the mail gets sent to [EMAIL PROTECTED] where a third header is added
(Delivered-To: ksamy@localhost)
Does this clear it up ?
The gist of it is, whenever qmail delivers a piece of mail (be it to a real
account or a .qmail alias) it adds a delivered-to header to suppress mail
loops.
