I very rarely received any spam until late July of 2016, when Fidelity found some of my personal info on the Dark Web. While there was no actual account hacking, Fido did wash my account and gave me new account numbers, after I got my hard drive cleaned (it was actually not working well and got replaced).
But that's when my spam email began flooding my email. It took a while for me to figure out how to filter it out. I set my spam filter to its strictest setting, which had the effect of sending some legit mail to the Junk Mail folder. I then had to get used to checking that folder for legit email, especially if I began corresponding with new, legit contacts. I use a PC-based email system, but I have to the web-based version to utilize the spam filter, another minor nuisance.
The spam has dropped off some, but I still see 2-3 emails in there per day. I can block domain names, but the spammers change them like every time to make them unique; it's like trying to scoop sand from the ocean! I'd like to use wild cards in the blocked domain names, but that feature isn't available.
