@ColinTheMathmo some people have had issues with emails from this domain bouncing because the domain is too new.

I'm seeing this from your mailserver in the log:
"JunkMail rejected - mail-s94.mailgun.info [184.173.153.222]:19893 is in an\nRBL, see Blocked - see http://www.spamcop.net/bl.shtml?184.173.153.222"

@chr Now 20 minutes and still counting - I've clicked the "retry" link, still nothing.

@ColinTheMathmo see this message: https://cybre.space/@chr/85524

you'll probably have to use a different email account, people have had success with gmail so far

@chr I don't have another account, I don't use gmail.

@chr Trying again, same username, different email, it tells me the username is taken, so that's in the system. Still no confirmation email though, and it's been 25 minutes now.

@ColinTheMathmo what's the new email? i'll update the account entry in the database by hand
