[Pymilter] Adding Recipient takes extremely long

[Thomas Spycher]

Hi Stuart

Thanks for your fast reply. It could be interesting to get some knowledge from milter/postfix insides. How does milter add an recipient to an arriving mail?
Is there a way to manipulate the whole raw header with regexp from milter?

In detail my script is going to replace all recipient addresses (to, cc, bcc) with the same address, but with a uuid4 and a + prefixed. This is due to trace a message trough the whole system and logs, even if it gets requeued.

Thanks for your help
