    Asked by koesger on September 09, 2016 at 04:20 AM

    Dear Support Team,

    in order to use our own smtp server our IT department need to know which ip address will try to access our system via port tcp/25.

    Could you please provide us a list of the mail systems which are used for sending the mails?
