Don't put vpopmail domains in control/locals. You'll mess things up.
There isn't a known solution to what was asked. Doublebounces go to
the postmaster of the server. Bounce messages refer to the name of
the physical server, and not the domain name.
You might be able to modify qmail-send, but it would be very difficult
to determine what hostname to use in the bounce message.
There's actually a patch to qmail-send that does this, I've attached it
to this mail. It was originally posted on the qmail-list if I remember
correctly. I've been using it for over a year, and it appears to work
fine. But I'm not the author - if it doesn't work for you, don't blame me.
What if there are multiple recipients that bounced?
Then there are multiple bounce messages.
What if it's a message one of your user's is trying to send to a
hotmail address? You don't want it to say that your server is
hotmail.com.
Well, I'm no expert - but the local mail server should only generate
bounces it the mail is directed to one of the local domains. Otherwise,
it should either not accept the mail at all, or relay it to the
appropriate MX. If this MX can't deliver the mail, it will generate a
bounce message on its own.

The snag is that the only sensible thing then must be to set bounchost to something neutral, like Mailserver. It cannot be set to domA or domB, as bounce messages from the other domain will then be utterly missleading. For the sake of argument, suppose that somebody wants to send mail to [EMAIL PROTECTED], but miss-spells the name and writes e.g. [EMAIL PROTECTED] He will receive a bounce message, but he will have no idea which message bounced, as there will no indication from where it come. So, his interlocateur Kvaksvik will be wondering why he hasn't received the message he is waiting for and thake his buisness elsewhere. Have I missunderstood something or is this really the state of affairs in 2003? Regards Sigmund.

Have I missunderstood something or is this really the state of affairs in 2003? Yes, I think I did missunerstand it. The above scenario isn't true of cause, as the bounce message will say Hi. This is the qmail-send program at Mailserver. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. [EMAIL PROTECTED] Sorry, no mailbox here by that name. vpopmail (#5.1.1) And then it isn't such a bad idea having the host name in the bounce message. Sorry, just a popmail newbie that hadn't had his coffe yet. Regards Sigmund.
