conditional rewrite of mail from matching recipient domain in postfix

  • 772

In postfix I want to create a (so to speak) rewrite rule to rewrite the "mail from" - field matching one specific from-address "[email protected]" to "[email protected]" (for use with aol smarthost), if (as a condition) the "To"-field matches *@aol.com"

I must do that, because aol denies to use another "mail-from"-address than the real registered account ...

is that possible maybe via header_checks?

    This should do it.

    /^From: (.*?)@gmail.com$/ REPLACE From: John Smith <[email protected]>
/^From: [email protected]/ REPLACE From: [email protected]

    Also, you don't need to postmap regexp files.
