I migrated our mail tonight, thanks a lot, btw!!
But also tried to connect free external pop server and another corporate pop server to my account. It worked at the beging of the day. But in the afternoon, it didn't retrieve any new e-mail, (though outlook express and web interface showed them).
What can it be? Where can I find logs of "Get pop mail"?
The only thing I remember to change - increasing allowed message sizes.
