Hello,
since users are able to put .forward files in their account, sometimes
when we write to internal mailing lists some messages get sent to
outside servers and once in a while the final destination user doesn't
exist (typo or other error).

I tried looking at the log files to find out who the user is but i can't
seem to find any clue in there about that. I can see the sender and
destination user but nowhere do i see .forward expansion. Any hint on
how to search for it?

We have a setup with postfix/amavis/dspam so messages get reinjected
into postfix if it makes any difference.

Anyone has a tool to simulate EXPN behavior? That might help find the
source of the problem.

Using :
find . -name .forward | xargs grep invalidemail(a)somewhere.com

is not an option unfortunately.

Thanks for your help.
