SMTP Mailserver config

[kittforhire]

Hi folks,

I cant figure it out. With changing my domain, the mailserver domain changed to kittforhire according to the settings (but seems like mail.kittforhire.com could be an option). So simple, so easy. Webmail works but the mailserver will not work. I cant get SSL running because letscrypt is insiting its an NXDOMAIN. Probably thats my whole issue already. Can someone confirm and tell me i am just impatient and need to wait until its going to work?

Thank you
