Yesterday my e-mail address was blacklisted -- again. I have asked my ISP to investigate -- again. I suspect that it is due to messages that someone has been sending in my name -- not from my computer, but from some other location with a forged address. I get to know this when the messages are rejected and bounce back to me, as has happened this month. I can get un-blacklisted with a large penalty, but then I may be instantly blacklisted again. OBSERVATION: Thankfully I also have (linked) web-mail addresses, so I am not shut down.
