I want to block emails that have not come from any of the following domains. au;ie;us;info;me.uk;co.uk;org;org.uk;gov;net;sch.uk;ac.uk;ltd.uk;uk.net;gb;eu;ca;de;gg;gi;hk;im;it;je;jp;ke;kr;mt;nl;nz;se;
I have tried in the content filter setting a block for SMTP Sender does not contain, but this is blocking everything. Can you suggest which one of the conditions I need to use.
Thanks
Malcolm
