Patching advice?

[Michael Menge]

Hi,

as far as i know cyrus duplicate detection only checks if the messageid
has been delivered to a folder. As long as you don't change the messageid
you can change the message befor you deliver it to cyrus.



Quoting Benjamin Donnachie <benjamin at pythagoras.no-ip.org>:
