Broken syntax in Postfix header_checks

I`m setting up Postfix to edit the headers dependent on the reciever. This is done through header_checks(http://www.postfix.org/header_checks.5.html)

The logic is as follows: If the e-mail is sent to "[email protected]" then we copy the From field and an paste it to the Reply-To field, the From field is also set to "[email protected]".

I have no experience with regexp but through some searching I was able to come up with the following:

if /^To: ([email protected])\s.*$/
/^From: (.+@.+)\s.*$/ PREPEND Reply-To:$1
/^From: (.+@.+)\s.*$/ REPLACE From: [email protected]
endif

This does not work. I'm not sure what's wrong with the syntax, but any help would be very appreciated.

Regards Erik

It looks like the accepted answer might mislead.

If you fight with if-endif in header_checks you should keep in mind the following:

If  the  input  string  matches /pattern/, then match that input
string against the patterns between if and endif.  The if..endif
can nest

from http://www.postfix.org/header_checks.5.html

Pay attention to "then match that input string". This means you can't operate any header inside the if/endif block but the one you use in if-statement.

The problem is that the header_checks are applied only one time for each email line, so the seconf "From" line (line 3) is skipped.
