For a few years I have been using SpamCop to bring to attention spamers that send me unwanted comercial spam.
Now for the last few weeks I am getting returned undelivered email and warnings about sending spam. The undelivered spam have my email address as the source, but the sending IP is not mine.
I even got a notice from SpamCop about my sending unwanted spam. Only the listed source email address on the spam was mine. I did not send it.
And when I checked the block list in SpamCop my email address came up with a foreign IP, it was not even an IP from my area of the US.
When I brought it to the attention of my email provider they just replied somebody was forging my email address as the sender to block their punishment/ detection.
At a loss as to what I should do next.
