I'm getting this too...coincides with me being overseas and needed email for job interview.
If TPG is actively blocking users, perhaps an informative email to the user would be in order?
I've changed my pasword, but fail to see how this will help.
I'll go have breakfast and see if it works when I return to the hotel.
You may need to change the SMTP server, depending on the ISP you're connected to. Please confirm if you're getting banned error message if so, changing your TPG account is one of the resolutions on this issue and it usually takes 30mins for the banned status to be lifted.
Let us know how it will go.
