Hello everyone, I did not know what title to put the problem, but I happen
to detail what is the drawback.
I use the header_checks file to insert a data in the Reply-To header but
depending on the provider it is added incorrectly.

/^From: (.*@primarydomain.com)/ PREP
Hi!!
I am using the prepend option as follows:
/ From: (.*@mydomain.com)/ PREPEND Reply to: $1
When the mail arrives I see that it does this way:

Never perform the update through the source code. I would like to know if I

Sorry for such a basic question but I couldn’t find a solution on my part.
I’m trying to block a Subject using header_checks but it’s not working.
This is my rule:
/^Subject:.*Invalid HTTP_HOST header.*/ DISCARD SUBJECTALERT
I used postmap to test the rule but not match.
postmap -q "[KIS] ERROR

Hello everyone the problem persists. Maybe I’m doing something wrong.
Step 1, I add the rule in the /etc/postfix/header_checks file
/^Subject:.*You may need to add/ DISCARD TMP_BLOCK
Step 2, postmap /etc/postfix/header_checks and postfix surcharge.
Are these steps correct?
