Cool! But it would nicer if there where a way to turn this on and off using the client, maybe sending a special email to oneself to control this? I mean, one day Joe User could be using MS Outlook, and the next day using a PDA/WAP or whatever? Or do the client advertise itself? Perhaps this should be done using a plugin system to bincimap? > The content of the message identified by a UID must remain unchanged for > each UIDVALIDITY assigned to the mailbox.

Yes, you are probably right. There are also transparent fs compression one could use instead. -- Regards // Oden Eriksson, Deserve-IT.com
