I use the OL2007 Trial. WinXP-Home, 3GB RAM 2.6GigHz P4.

I cannot get the program to send or receive mail. Something has changed and
I cannot find anything wrong with any setting: I have double-checked the POP
and SMTP names; set OL for no authentification (ISP requirement); tried
"Repair"; set everything manually, POP port is 110, the smtp port is
25...anything else...?

I use the same program on my laptop and these same settings produce a
working in-out connection.

There must be *something* else incorrectly set. I had been sending and
receiving.
