Blocking mail from a domain to specific users

tmbm50
A client of our has a requirement to block all email from facebook except for specific users.

There doesnt seem to be a good way to do this without unfiltering other unwanted messages for these users.  Unlike web filtering rules, there doesn't seem to be a way to build exceptions with an "and"...just an "or".

I can stick facebook.com in the sender blacklist, and then exclude users from that sender-blacklist.  But the sender blacklist has many many more entries besides facebook that these users will want to block.

Any ideas?  It would seem to be a simple function but I'm not seeing any way to do it.

    Again, it seems easy.  Make it a company policy with a formal warning the first time, etc.  There's no reason for employees to have the company email be their email for facebook.  In 'Logging & Reporting >> Mail Security', search on "Top addresses by domain" to quickly see a list of the guilty ones.

    Cheers - Bob

    If it was as easy as making it company policy who would need an Astaro http://www.astaro.org/images/smilies/wink.gif?  The point being most policies need to be enforced....hence we buy things like Web filters, email filters etc.

    Anyways, here's hoping Astaro spam filter will catch up with others in the field.  For now we are trialing postini which has a bunch of cool things we didnt even know we needed.

    This seems like a job for the backend mail server and not the mta. Would be interesting to know your final resolution.

    Our final resolution is Postini spam filtering.  It has very flexible spam profiles, similar to what astaro can do for web filtering.
