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.
All unverified accounts a wiped after 24 hours. You can try again once that’s passed.
I appreciate that. :) I was able to move a domain over to protonmail and it worked this time for me. Thanks!
