Reason #9751 not to use sendmail
If you map a domain (x.com) to a single account (xuser) and then send a message to a@x.com, BCC to b@x.com, only one copy is delivered to xuser's mailbox.
Therefore, it's impossible to implement a correct multidrop account in sendmail that you can later pickup using fetchmail or similar software.
Hi Roberto! it's a long time eh?
Well, what you wrote it's not entirely true...I'm an ex-sendmail fan :-D (go postfix!!) and I've used sendmail for multidrop and be able to overcome this problem.
In /etc/mail/virtusertable you have to make the "catch-all" entry like this:
@x.com xuser+%1
Then, if you use fetchmail to download the emails you should add this parameter to it:
-E X-Envelope-To
And that's all!
Nevertheless...Postfix is *great*, don't use sendmail!! :-D
Reason #9752 not tu use sendmail: it's weird ;-)
Ok, I didn't know that :-)
Now, where the hell is that documented????
From what I found on google, wouldn't that deliver to xuser-a and xuser-b instead?
