Good morning everyone, I have been experiencing a problem since I installed the new server and it is none other than when I started to invite guests to it, there came a time when it did not accept me to send invitations to accounts created by other users or to accounts that are Gmail or Hotmail.
It only lets me create accounts from the server to hi2.in accounts or something similar.
I’ll pass you a screenshot so you can see the error message and if someone can help me solve it.
