We use Exchange Server 2010 with Sophos Puremessage SPAM & ANTIVIRUS checking.
Our clients use Apple Mail & MS Outlook for Mac to access the server in cached mode.
Some of our internal messages i.e. emails from and to recipients within our organisation are junked and our end users don't notice this and IT Staff get ear ache about how the system is hindering them from working
Is there a central way to reduce or whitelist internal users? also many normal emails from other schools which we work close with also get junked. I have checked many servers including our own using MXTOOLBOX BLACKLIST checks and were not black listed and neither are any of the other schools.
I feel i simply need to turn down the sensitivity or to whitelist the domains
Any advise on this would be much appreciated
