Why are you using perdition, when you could be using Cyrus' "murder"
clustering which will work to the same end, with added bonuses of
being able to share folders between users on both servers, easier
administration, etc.

I found the "mailutil" program, which is distributed in the UW imapd
distribution, particularly well suited for this. It allows you to
transfer the contents of one c-client supported mail hierarchy to
another, such as a local mail store to a cyrus-hosted IMAP space.

Hey all,

Going this same direction... With our previous mail system, we used

weekly notification reminding them of the messages they had in these
