Hi Bob,

Thanks for  the explanation.

I would seriously consider delivering the incoming messages to a
script/program for further processing, instead of adding a POP3/IMAP layer.
Postfix is well suited for to do just that. I simply cannot come up with a
single good reason for "wasting" resources by stuffing an POP3/IMAP server
in there, especially when it's so easy to configure Postfix to deliver to a
command.
