Sendmail - Masquerade
 

SSH to RH Fedora Core 6 Server from Unbuntu 10.04 desktop.
(yes I am going to upgrade from FC6)

I rem'd out several lines in my sendmail.mc (then updated) to remove the "masquerade" lines. I have a spoofing problem and thought I would try this.

Now, email seems to work ok but in addition to the test message (which comes through) I get a qmail-send mailer-daemon which says it was not deliverable (even tho it did deliver it).

Here's the qmail daemon notice:

"Hi. This is the qmail-send program at ip-xxx-xxx-xx-xxx.ip.secureserver.net.
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.

<duan@ip-xxxxxxxxxxxx.ip.secureserver.net>:

Comments? It seems to work ok if I could eliminate the error message... I think.

Maybe you could just filter that extra mail and divert it to null or something?
