[Zope] sendmail control?

Does anyone know if or how you can create, destroy, change passwords, and possibly other things, to sendmail (IMAP) accounts remotely? I want to use WorldPilot, but it uses sendmail's usernames and passwords, not Zope's. So I'm interested in something that can synchronize those two things. Or, just flame me that it would be the biggest security hole since NT :) Marc Lindahl bowery.com
