Bounced mail problem

emails bounced show as if coming from different domain on server.

I just found out that when people send emails to a domain on our server - and if the email bounces for some reason, the end user sees the email coming from a different domain.

Here is an example:

- The server is running Qmail (on Linux ES)
- The linux server has 6 domains, each with their own IP address
- Example domains:
###.###.###.##1 domain1.com
###.###.###.##2 domain2.com
###.###.###.##3 domain3.com
###.###.###.##4 domain4.com
###.###.###.##5 domain5.com
###.###.###.##6 domain6.com

Now, lets say someone sends and email to "[e-mail]", but that user account doesn't exist. The user gets an email response that looks like this:

Hi. This is the qmail-send program at domain1.com.
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.

No matter what domain someone sends an email to, if it bounces, it shows it is coming from [e-mail]. Is there a way to correct this?

IIRC, we had this same problem, and we weren't able to see where to tune this either. I believe it basically uses your default domain (domain1) as the "master" domain for system messages.

Not much help to you, I know, but I wasn't able to find a solution to that problem. It also wasn't a very high priority problem anyway, so it went by the wayside before we switched to PostFix.
