We can trust nobody these days...

My very favorite (so far) of that sort was an email advertising women who would pretend to be naked while talking to me on the phone (yipee!), which pretended to be from caroline {at} philringnalda {fullstop} com. You would think that I would already know her better than that before giving her an email account off a personal domain, wouldn't you?

But for the "from the admins of your mail server" ones - I had a free account that I used as a public address for several years. Virus writers started targeting it, so I threw away anything from admin@ unread. It took me several days after I started having trouble connecting to the POP server to discover that the service had shut down, and some of those mails were really from the admin saying that they were shutting down. Ah, well.

Phil: yes I already know about admin[at]procos.com (there I work as a employee), also stuff[at]procos.com and others non existing. There will be a day they hit a correct name [grrrr]. But handling that I had to modify my mail rule sorting out the procos.com domain to a coworker folder...
So for now: awating the mails from admin[at]gmx.net, think I'm well prepeared (hopefully) ;-)
