I have received one of the dreaded "User email@example.com is banned from using SMTP AUTH due to previous abuse" messages.
I saw that my account was compromised a few days ago due to all the rejected spam emails coming back to my inbox. I immediately changed my password which stopped my account sending spam, but now I cannot send emails and I get the message above. I can only receive emails.
It looks like lots of other folk have had this problem recently too. Can TPG please remove the send block on my account?
