This is not ethically correct. Someone might be stupid enough
to share their bank account and password on the email. But he/she does
so trusting that the mail is secure. We morally do not have a right to
look at the contents of the mail without the knowledge and the consent
of the sender *and* the receiver. No one can stop you from doing it,
but it is a very very bad thing to do.
What you can do, however is, something like mail filter that
exim has. You can automatically discard messages with specific terms
in the header/body of the message. Again, it is not a fair thing to
do. But if you are working in a corporate and want something like Data
Loss Protection, then it is a different aspect and best to get some
support from an expert in the industry.

These are doable with most mail servers. In exim, IIRC, there
was an acl_smtp_mime config that you can setup based on the file name.
The other option is to do what Girish said - Based on the Content-Type
SMTP header can be used. But from what I understand, there is a format
called TNEF used my Microsoft which has caused trouble. So, handling
TNEF mime types is best left to proper TNEF decoders. Thanks
