[rt-users] RT 3.0, postfix, wrong outgoing address

[Jorn Hass]

This behavior is actually correct. What you see in the maillog file, is the
"envelope" sender, and not the "from:" that you see in the email itself.
When you view the message at the receiving side, it shows up as
rt@<wherever>.
 
I think this is actually a security feature of postfix, to always reflect
the correct local sender (the user running apache in this case), rather than
try and take it out of the email itself.
 
As I do not want people to see this envelope sender, I have used the
sender_canonical function of Postfix, to rewrite all from
httpd@<host>.<domain> to rt@<domain>, which then makes it look better in the
envelope. This has the side effect that it will also send failures bounces
back to rt@<domain> (unless failures-to has been set) which might not be
what you want, so you might want to rewrite to something other than rt.
 
I can see that RT sets the reply-to correctly, so unless you have an
absolute braindead mailprogram, there shouldn't be any problems.
 
I do see that it does not set "Errors-To:", which is maybe something that is
needed to prevent the above side effect of failure messages. Any thoughts?
 
I hope this helps.

[snip to save space]

I suppose I could put in a postfix rewrite rule for apache to be rt instead,
but then what about rt-comment? (or is simply mapping apache to rt
sufficient?) 

I would have thought that the above two Set commands would do the trick.
What else am I missing? 

Thanks,
