All emails have the same or similar subject, weight loss pills and workout suppliments. Lol.
I'm using Thunderbird as my client...
I have just been googling it and it seems theres no real way to stop this apparently. So I have just set up a filter for now to dump them into the junk folder. Some sites did say it will eventually stop. I hope. My business email has been pretty clean with no spam up until a few weeks ago and its quite bad now.
