You retrieve email from your ISP with SMTP?  Is this a new
experimental version of the SMTP protocol?  The SMTP I know (see:  is for moving email between
servers--both sending and receiving. POP3 and IMAP are for managing
received messages and downloading messages from a server to a client.

Anyway, first things first, can you telnet to your ISP's SMTP server on port 25?

Have you checked your DNS resolution?  What does your ISP say?
