Hi,

I'm using postfix snapshot-20001217 with the per-user-uce-patch (thanks to
Jozsef Kadlecsik this way) on my primary mailserver. The anti-UCE function
works really great, but now I had a new idea. Since many users don't want
email delivered by spamrelays to be bounced but want to be warned and able
to filter them on their mailclient, I had the idea to insert a new
headerline into the mail if it was delivered by a host listed in any url.

My incomplete idea of a config looks like this:

+--[ main.cf ]---
|smtpd_restriction_classes =
| class_rss_reject,
| class_rss_note
|
|class_rss_reject = rbl:/usr/local/etc/postfix/rss_domain_rbl
|class_rss_note = ...
|
|smtpd_recipient_restrictions =
| permit_mynetworks,
| check_recipient_access \
| regexp:/usr/local/etc/postfix/user_restrictions,
| check_relay_domains

+--[ user_restrictions ]---
|/^berni.*\birkenwald.de$/ class_rss_reject, permit
|/^spamnote\birkenwald.de$/ class_rss_note, permit

A mail sent to spamnotebirkenwald.de by a relay listed in rss should not
be bounced, but have a header like

X-RBL-Warning: ($ip) in RSS. See http://www.mail-abuse.org/rss/

inserted. If possible it would be nice if several headers were added if the
host is listed in several lists (e.g. RSS, ORBS, RBL)

Any ideas how to realize this?

   bye bye
