I will at first, I need to start as soon as possible, this means I'm postponing the issue of finding out how to have on my mail gateway box virtual users associated with the real smtp addresses I'll have to extract from exchange (that at least I already know how to do easily, directory export on exchange 5.5, ex2k+ from active directory). For now everything will go into the "amavis" user bayes I suppose. > I use a public folders for message submission, users can see > the folders, create I suppose a public folder in order to not needing to access indiviual mailboxes with imap ? That's a another problem I've yet postponed: 90% of our mail sits in public folders anyway, where a combination of ACLs, cdo agents and custom forms simulates group mailboxes, by extending that structure I can easily have a "Spam" folder in any group "mailbox" (PF group). This means I'll have to pull more than one folder with IMAP (not a big thing) but at least users won't need to change behaviour if later I should go the "individual user bayes" route (with any real and any fake "group mailbox PFs" will have one individual bayes). > Are you thing of having the users "push" the messages to the > relay server or pulling > the message out of Exchange from the relay server? Pull with Imap I think (another possibility would be extract with CDO/MAPI and push, but that has the drawback of more encoding work). At least until migration ti ex2k* In the meantime I found: "Messages sent by an Internet user are not converted. Instead they are retrieved by the IMAP4 client in the format the message was composed in."

Still I'd prefer going the analyse first, insert into bayes later route, since it needs to store only bayes data, not whole emails (potentially huge db). But that has the counterpart of needing a spamassassin patch. For me it is a moot point for now anyway, not enough time, I'll try the imap route first, think about a better solution later. > Cheers, > matt Thanks to you!
