FYI: I was given the impression that pcre has better performance than regex in
postfix, if that is something relevant to you.

Since I'm using AlmaLinux, a derivative of RHEL, it does not have PCRE because
Redhat decided to remove it entirely from RHEL.
Thus, I had to convert all my "pcre:" into "regexp:", like the above.
I'm using a similar flavor of RHEL and
dnf -y install postfix-pcre
worked for me. Is that

Why everyone feels they need regular expressions for this is a mystery.
Hi
Please send info like:
postconf -m
Probably you dont have pcre
try postmap -q your_ask pcre:/etc/postfix/reject_domains

What is the error message logged before that?
Does your postfix support the pcre map type?
Maybe try regex:

getting: 451 4.3.5 : Sender address rejected: Server
configuration error;
Obviously this is a configuration issue. I've tried following these

HI,
I have a check_sender_access restriction that blocks many TLDs like
.red and .space. Problem is that we have one legitimate .red customer
