Email not sending
I think ive been hacked. I have many strange addresses in my sent & draft folders. I have att.net email address. I changed my password. I can receive email but not send any. I've tried thru the Yahoo app on my Android phone & the Microsoft mail server on my PC. I spoke to at&t & they gave me a hack helpline which has been busy for 2 days. I can't surrender this address it's on my business cards. Please help!
