295243Recipient rewrite based on sender
- Sep 4, 2013Hello list,
I have been asked if the following is possible somehow with postfix, but
as I'm quite unsure I try to ask the "gurus" :-)
The goal is something like a conditional recipient rewrite. The
condition would be the envelope sender.
Like: if sender is XXX rewrite the recipient to YYY but only if original
recipient is ZZZ.
The only way I see so far would be to use a postfix pipe to handover all
mails from defined sender to a script that does check the conditions for
recipient rewrite. But with the downsize that every mail from this
sender has to be piped through that script. Even those that would not
have met the conditions for rewrite.
Is there a way to achieve this without piping to an external script?
thanks for any idea
