Hello,

I have already installed iRedMail without any particular difficulty.
Since a few days I have installed on a new (virtual) server and restored on it the backup made on a physical server.
I recover well all the users/emails/rules etc...

With this new server I can send mails without difficulty.
But I don't receive mails from everyone.
Hotmail, Gmail I receive. But from other services I don't receive.

Is this a known problem?
Do you have any research leads?

Thank you very much,

Jean Philippe Boulanger
