After days of frustration, checking every character ibn every config file I give up on the email issue for u.fail.. :sad_cat:
Yesterday I got a domain for a (replacing) Lemmy instance!
I think something with the initial setup went wrong on u.fail and I can't seem to fix it :sad_cat:
The new instance that is fully working is running on https://Geddit.social
So i'm gonna close U.Fail soon since it was really a fail :blob_derpy:
I hope you undedrstand.. I really tried
Please see my Mastodon post for more info about this.
For me, the email verification goes straight to the inbox so no issues and the current domain I really like it.
