Re: [exim] Router for specific outgoing messages?

Nothing spectacular. A friend wants to bill a client via email.
Normally such messages contain a PDF attachment, but this one client
will only accept it if the PDF is first converted to JPEG format.

Once I have the router, I plan to re-use a previous transport that
pipes the message to a Perl script, which will detach, convert and
re-attach the attachment, after which the message will be sent back to
Exim via BSMTP so that it can finally be sent on its way.
