Hi,
I would like to tag/replace each message Subject: with some custom
pattern and leave the rest unchanged.
I'm using following header_checks rule:
/^Subject:.*/ REPLACE Subject: PRE $1
but I get a warning:
Aug 17 19:03:57 mail postfix/cleanup[20807]: [ID 947731 mail.warning]
warning: regexp map /etc/postfix/header_checks, line 1: out of range
replacement index "1": skipping this rule
the same rule without $1 is working fine. I'm using postfix 2.5.7.
Any thoughts please?
Thank you,
Stefan
$1 refers to text inside the first set of parenthesis "()".
You don't seem to have any, so $1 is undefined.
/^Subject: (.*)$/ REPLACE Subject: PRE $1
