Hi PMG community
All days and at regular interval times the perimeter PMG functioning for our email system is blocking all the attemps in which an anonymous sender is trying to relay email from our domain to even valid email destination domains, I share you one of the notification emails to depict the case:

Is this a normal pattern? or Is it derived from a PMG's misconfiguration? the most part of the time I'm wondering about this.
I keep in pending, have a good day.
