recently i am having problems with sending emails from my desktop, via thunderbird. it keeps asking me to sign in with my new password. however i have not changed my password with virgin. i can send an email from my phone, so i know its not virgin. i have spent 3hours reading up and checked the server and outgoing settings, and changed switched adjusted what i could see, and set them back to the original settings, which in effect meant i have done nothing, and all of a sudden it works again. this did happen a couple of week ago, so not sure what's going on, and i really haven't got a clue what im doing, so any help or advice would be appreciated.
