other maps that
Thank you all!
It is working now as I had expected.
One question, does postmap needs to be run against the cidr file? Or is a

Unlisted IPs access to send mail thru this server (you have asked me not to use

We have a situation where some party is harvesting our employees'
mailbox names and using them for a directed brute force attack against
our SMTP servers. In order dodge this we have undertaken to rename of
user mailboxes. However, we use the imap service to authenticate for
SMTP delivery and so

Listed IPs are allowed to send mail where? To your local users? To
any destination?

Ok, my apologies. It seems some of the answers focused on "it doesn't work like

What I need is to have any IPs listed in the /etc/postfix/access file with a

You could do this with seive.
But it seems like an odd rejection. I am sure I am not the only person who

Did you mean:
1) No Subject: line. For this case you need an external content
filter (Milter, smtpd_proxy_filter, filter).
2) A Subject: line without text. Postfix can match this with
header_checks
Hello list,
