Discussion:
smtpd_proxy_filter by recipient domain?

I would like to send messages off to different smtpd_proxy_filters depending
on the recipient domain and I don't see how this can be done with Postfix
currently.

Would it technically be possible to do that?

Speaking in terms of interface I have something on my mind that expands
access(5):

smtpd_recipient_restrictions =
...
check_recipient_access hash:/etc/postfix/proxy_filters
...

# /etc/postfix/proxy_filters
example.com smtpd_proxy_filter=127.0.0.1:10024
.example.com smtpd_proxy_filter=127.0.0.1:10025
example.org smtpd_proxy_filter=127.0.0.1:10026

There can be only one smtpd proxy filter per smtpd process.

Proxies process messages, not recipients. Envelope splitting happens in
the queue manager. What you are wanting is not possible pre-queue.
