I've never heard of either, but when I configure my IMAP server and
put any mail client to it, as soon as a mail is delivered, the mail
client is notified.

I don't use biff or comsat or anything similar.  mine is a simple IMAP
server pushing it.



I'm anxious to really hear what this is...  I don't have any POP3/IMAP
enabled smartphones to test with.
