Since a few days i got the log on our Securepoint Firewall full of trys to connect to port 587 from the IP of my omv System.
In this case some other Services, not omv, Printers Software etc. are not possible to send their notifications because there are to many 587 Connections in use.
I cannot stop this until i completely disable the mail notifications in omv.
Any one a solution for this?
