[RAS] email problem on nebka?

[Christian Zimmermann]

I have received a few email bounces recently indicating that nebka is 
blacklisted by barracuda. Each time, I went to the barracuda website and 
asked to be whitelisted. It is still going on.

Thus I google for barracuda problems, and come across this:

http://andrew.triumf.ca/barracuda-problems.html

Seeing this, I try to understand whether nebka is subject to any of the 
discussed issues. Now, aras, aacis etc. resolve into the email 
addresses of Ivan, Thomas and me. However, when Ivan and Thomas are 
unreachable, messages bounce back to the sender, even if it is a pretend 
sender. It seems to be what triggers barracuda to think nebka is sending 
spam, it is in fact error messages replying to spam.

I see several of those messages in /var/spool/exim4/input, for example:

What are we to do? it looks like the spam filter Thomas installed on 
openlib.org is creating problems upstream...
