Gday and thanks for the response. As I said in my initial email, the unsolicited emails appear to coming from webmail. I don't normally use webmail, I use Thunderbird on the desktop or the built-in mail app on the iphone or ipad. My reason for saying this is that the emails were in the "sent items" folder on the TPG webmail client. My email signature (which I also have never used) was set to the text of the unsolicited email - again, on the TPG webmail client. Various settings had been changed in my webmail settings, I presume to support the unsolicited email transmission, and which I have since corrected. I cleaned up my TPG webmail by emptying the "Sent Items" folder and removing the signature text, as well as resetting my webmail settings. Then, as I said in my original email, I changed my password. I have not seen any more emails in my "Sent Items" folder (on TPG webmail), so I'm guessing they have stopped coming from there. However, if I attempt to send an email from Thunderbird, I still get the above error. So my account is blacklisted. That is what I would like to have fixed, please! Regards. ... View more
