We just purchased an Ironport C150 and are in the process of testing it out and getting our setup completed, one of the things we want to do is reject incoming mail if an attachment has a certain file extension to it (ie, .bat but we have about 20 or so we want to reject). I can't seem to figure out how to get that accomplished and the documentation doesn't seem to help much, can anyone point me in the right direction to do this? Thanks.
Also don't forget to apply it to a mail flow policy that the mail will actually apply to if using multiple mail flow policies.
The ironport will do a first match on mail flow policies, so if you have multiple policies setup and you want to block only for one of them, make sure you have your policies ordered properly so that it will apply it.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
