I wonder how much an email does cost?

It's using server resources on every hop it makes to the final mail server. It's probably a fraction of a fraction of a cent from end to end but the sheer amount of unsolicited spam emails that get generated and sent around must cost a somewhat substantial amount of money overall.

I had that issue only once with Gmail and mailing list emails. I'm subscribed to an IBM mainframe listserv and for some reason it started marking them as spam without any notification. It wasn't until I realized that I haven't seen them in a few weeks that I found them in the spam folder. Overall gmail is pretty good about it though. At work, we have exchange and a surprising amount of spam/phishing stuff gets through. I'm not sure if that's so much on Microsoft though or our own IT departments configuration of the exchange server.

I'll have to set up a Yahoo test account. I never tried to see if it worked properly with the email reply feature. (Test in production!)

Edit:Set up a Yahoo account and ran some tests. Seems to work fine with email replies.

    It's just how it's got to work. The body could easily be encrypted, but it needs to be seamless. PGP never really took off, unfortunately. Sometimes I think it's a useful thought exercise to pretend an email costs the same as postage stamp. Do you really need to spend that money to just tick off... more

      • Good question... Probably what you're thinking. - Puckdropper, Fri Aug 25 2023 6:05am
        I'm sure somewhere you can find stats on how much stuff is on the Internet backbones that no one actually wants. Spam, the Nieman-Marcus cookie recipie that's been forwarded 35 times without being cleaned up, etc. It's actually quite a bit. It could be that it's an exchange server... Yahoo! and... more
        • Yeah, it's definitely an Exchange server - Erik_, Wed Aug 30 2023 9:54am
          It's just been so long since I've done IT/SRE work besides just development that I wasn't sure if maybe MIcrosoft had their own spam filter that they do on top of whatever your local Exchange server has set up. I guess thinking about it now, that would probably annoy a bunch of IT workers who are wondering... more
          • So now we know--email sending is cheap (like stealing) - Puckdropper, Wed Aug 30 2023 5:09pm
            and the receivers waste around $.95/message (like those being stolen from) and the only real solution is filtering (like theft prevention) but that takes resources (like buying locks does) and everyone except the spammers (thieves) would be happier without it. I really didn't expect the analogy to... more
