This is a new domain on an IP that was fairly recently assigned to it. All main email providers blacklist anything that is not gmail, outlook or aws by default. Nothing I can do about it, other than becoming part of the problem and paying them to host this instance’s email.
I too have tried to sign up to no avail. I just never receive any emails for verification. I’ve used both gmail and a custom domain on Google workspace (actually thinking of migrating that to mailbox.org or protonmail)
I used proton mail and had no problem signing up
I have some bigger plans for email setup, but will still have a look at a more thorough setup. Don’t have an ETA, unfortunately - life stuff is a big busy at the moment.
No worries at all. I’m patient :). As a former sysadmin and current Cloud Systems Architect, I understand. I’m going to migrate one of my domains off of Gmail to a new host to trial it and I’ll try using that email once I get that done. Thanks for hosting this because I don’t have the time to currently. :)
