OK, BlackSheik, when you say you can not send e-mail, do you get any error message ? Can you make a screenshot and post it in here ? We need to see what Thunderbird is reporting to you when it's unable to send a message... there must be some error message you are getting...
Btw, it's pretty late, and I have to get up early in the morning... so... I'll check on this therad tomorrow morning...
