Hello,
I would be really thankful if someone could clarify it, please. It says the
following, "Postfix works as documented in regexp_table(5) and
pcre_table(5), i.e. each query stops at the first matching rule. Now the
following two rules are in conflict:
/^From:\s*assistant\@gmail\.com$/ REPLACE Subject: New Report.
/^Subject:\s*$/ REJECT Empty subjects fields are rejected.
I doesn't stop at the first matching rule where the subject is replaced.
No, it replaces the From: header with a second Subject: header. The
original Subject: is untouched.
At that point, processing of the From: header is stopped and postfix
proceeds with the next header presented.
Instead, it stops at the second matching rule where empty subject fields are
rejected. Thus, it causes trouble, instead of accepting mail from
header_checks does not check headers added by postfix.
And REJECT always wins. Rule processing is stopped as soon as a
rule resolves to REJECT, and the mail is rejected at the earliest
opportunity.
assist...@gmail.com that is being sent with an empty subject field, it
rejects it as per the second rule. How do I make it stop at the first
matching rule? Would highly appreciate any pointers / suggestions /
assistance at all. Postfix 2.9.6. Many thanks!
What you appear to be trying - if the mail is From some particular
address, replace the Subject: - cannot be done with header_checks.
You can probably do this with MIMEDefang or another milter, but the
actual implementation is outside the scope of this list.
