When I try to send the verification email, I received this error:
2023-06-17 17:00:16.016 +00:00 [Error] “Your IP: ... : Your domain example.com is not allowed in header From”
MailKit.Net.Smtp.SmtpCommandException: “Your IP: ... : Your domain example.com is not allowed in header From”
The ip is the WAN ip on my router. The domain resolves locally.
