Terrorb, I see you have gotten the same results that I have: nothing.
Up until now, I could SEND email using Thunderbird, but not RECEIVE (although my other non-x10 accounts work just fine). Just in case it was a T-bird issue, I tried the account settings in Evolution, and got the same results: could send, but not receive.
Today, I cannot receive OR send. The problem has gotten worse, and no response from anybody on any of the threads about this issue (yours, mine, and one other).
We have tried being nice, with no results. Now what do we do?
