You'd have to build separate plugins for POP3 and IMAP, and even then it becomes tricky since there's no simple hook for catching when client gets destroyed.

Such a plugin might itself be simply a standard plugin..?  The motivation being to offer the ability to create plugins to those who are nervous of using a compiler, and of course to reduce the ability of a badly written plugin to kill dovecot?

I've been thinking about adding a scripting language plugin to Dovecot. Perhaps even using one of the existing generators that are supposed to make this easy for multiple languages, such as SWIG. But this is pretty low priority currently..
