I own a domain which I also use for email.
I get lots and lots. The server spam bot tags most of them for me which is easy to fliter out, but it’s the the “undelivered” emails I get from assholes using my domain to spoof the return address that really annoys me. There isn’t much I can do about that.
Occasionly I miss and important email becasue it gets caught as spam, and that REALLY annoys me.
Once when travelling in Vietnam a couple of years ago, we went into a restaurant, and one of their claims to fame was “free internet” while you dine. So after we were done, I went to check my webmail. The guy ushered me to the internet cafe area and sat me down. He explained that I wasn’t to close any other applications that were running on the machine. So I start surfing, well tried to, but after 2 mins to open a page I thought I’d see what these apps were. There were thousands and thousands of emails going out on that machine. I looked around the room, all the other PCs were doing the same thing.
I won’t tell you what I did about it.
