Hi,

I've setup two amavisd-new "instances", for "authenticated" and "the
rest", according to
http://www.ijs.si/software/amavisd/amavisd-new-docs.html#dkim.

Basically, this uses a default content_filter for "authenticated" and
a match-all FILTER at the end of smtpd_recipient_restrictions (after
e.g. permit_sasl_authenticated).

But now I want to use smtpd_proxy_filter instead, so amavisd-new could
really reject mails, instead of only bounce them.

Unfortunately I've found no way to accomplish this, apart from using a
special port and smtpd instance for "authenticated" smtp.

AFAICS I need to somehow overwrite the smtpd_proxy_filter setting in
smtpd_recipient_restrictions - after "authenticated" has been
permitted already.

Would it be possible in general to have something like
option_set smtpd_proxy_filter=amavis:[127.0.0.1]:10024
for the smtpd_recipient_restrictions chain?

The FILTER-catchall that I'm currently using does basically this: it
overwrites content_filter. Unfortunately this only covers
content_filter and not the options in general.

I hope there's a solution.
