ok, the problem is that postfix remove the +whatever . I've done some
researches on this, but actually i didn't found a solution. In case of
being OT just ignore my reply, but maybe someone can give a hint on this
issue.

My tests:
sending fom command line to port 10025 (means bypassing amavis)

testing with

sendmail -bv user+spam at foo.org

as mentioned in http://www.postfix.org/ADDRESS_REWRITING_README.html
gives, the following.

just for info: even to me the lmtp transport to amavis was a new feature
i read in the /usr/share/doc/amavisd-new/README.posfix.gz (Debian Lenny
amavis
1:2.6.1.dfsg-1) so i tried this setup instead of tcp. Time doesn't stand
still ;)
But as you said, it is not the problem.

This is enbled in amavis.

Thank you and best regards
