When I switched over to TotalChoice, I was not made aware of this in my Terms of Service and would not have switched if I had been. My expectation of a hosting provider is to allow the subscriber to have control over the enviroment, not some of the environment. I would have to agree with the other users that this feature should be at least configurable or optional.
If you insist on having it, I believe that a better option than pure filtering of certain attachment types would be the use of virus protection. This would allow in non-virii and provide a notification if an e-mail was received that contained one and was destroyed. I personally run virus protection locally and do not expect my Hosting provider to do so.
I discovered this issue only because I was trying to transport some files related to some of the work I do. The filter did not merely remove the attachment, but the entire e-mail was lost, so I would have had no idea the e-mail had been sent if someone else had sent it.
