its not gmail its meta.ua

It likely arrives as spam there too :)

I didn't even get it in spam

If you can email hello@lynx.boo with the email address you used it would be helpful for me to determine what happened to the email. I'm hosting my own SMTP server so I don't doubt that:

1) I screwed something up (most likely) 2) Your email rejected it because it's some no name ip with no reputation.

I tried my email address with my own domain, my @protonmail.com email address, and my @[very-good-"reputation"-university].edu email address. None worked. Eventually I tried my @gmail.com address, which worked.

I'll check the logs! Thanks!

this address has a 25 year reputation ))) it's just that now for some reason many are surprised that someone uses something other than Google

It's not your servers reputation that's the problem it's mine. Your server is likely rejecting my email.

But I'd have to check the logs.
