Clients having emails junked in outlook and Apple Mail

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

Great response time

Ill take a look into this, many thanks
I found the agents and they were all enabled. I have disabled content filtering agent as Sophos is doing that.

Should i disable all of them if Sophos is doing IP Block and Allow for all types of senders?
Hi, sorry for delay in getting back to you.

Generally yes, if you have a third party anti-spam filter it's recommended to disable all built-in exchange anti-spam agents.
Hi Andy,

Thank you for your advise, i have disabled the Exchange agents and Sophos Puremessage is intercepting many more nasties now

Im unsure how i can stop certain things going into Junk but i am going to try get around the client machines and make sure that the junk filters are not on
Very helpful and rapid response
If all your machines are on a domain you can actually use Group Policy to disable Outlook's own junk-filtering system. Unfortunately I'm not aware of any way to do this on Macbooks so it will need manually amending on there.
