Postfix rewriting subject for specific addresses
I would like to add a tag to all email messages sent to a particular address. I have tried to copy examples from the web, but can't seem to get it working.
Here's what I've done so far:
Add to /etc/postfix/transport
email@example.com rewrite:
Add to /etc/postfix/master.cf
rewrite unix - - n - - smtp
-o header_checks=pcre:/etc/postfix/rewrite_headers
Create /etc/postfix/rewrite_headers containing
/^Subject: (.+)$/i REPLACE Subject: [Example tag] $1
If anyone can see where I am going wrong, please advise.
Thanks,
James

You should be able to do this without a custom transport, using built-in header checks.
Add to main.cf:
header_checks = pcre:/etc/postfix/rewrite_headers
Your rewrite_headers file will have the existing rule wrapped in a conditional:
if /^To: email@example.com$/i
/^Subject: (.+)$/i REPLACE Subject: [Example tag] $1
endif
This should handle everything without the need for a transport config.

Is this also going to work if I want to change the sender of the mail for specific recipients?

Thanks for the tips. Unfortunately for me, my postfix config doesn't work as per documentation. header_checks doc says the header is checked in one bunch, not line by line. But this doesn't work accordingly to my config. So your tip doesn't work on my config.

There was a mistake in my config example.header_checkswas set to a file path, but as it contains regex rules the path needs to be prefixed withpcre:
