I am having a problem with mail I am getting mail ok but not able to send any as I get the message "the username or password for my mail firstname.lastname@example.org @smpt@talktalk is incorrect"
When I enter the password it verifies it but still cannot send mail help please.
Have you tried removing the account and then readding it to your mail app using the details in the Imap pop settings article?
You're very welcome. I'm delighted it's working for you again. Thanks for posting back to let us know.
