We have a standard third party antispam solution for our email. We do not want anything else scanning the mail and perhaps blocking email. The problem now is that we often get this message:
srv-001.DMN-ELISYS #5.2.3 smtp;450 5.2.3 Msg Size greater than allowed by Remote Host
I thing there is some filtering enabled, there is nothing configured on user level or default Exchange lever for maximum size, so I do not understand wat causes this message.
