I just can't seem to figure out why header_checks are not being evaluated. I'm on Ubuntu 12.04, postfix 2.7, dovecote, spamassasin, clamav, amavis.

I add following line to /etc/postfix/main.cf :

header_checks = regexp:/etc/postfix/header_checks

And here is header_checks :

/From: .*/ REPLACE From: [email protected]

To test out regexp :

#postmap -q "From: <werwe>" regexp:/etc/postfix/header_checks

which evaluates correctly and give me return output of :

REPLACE From: [email protected]

However, when I try to send email from commandline or from php webpage, postfix will not replace the From header. I'm stumped.
