If you want to block incoming mails w/non-desirable attachment "types",
you can do so via the Exiscan-ACL patch. Simply put something like the
following in your DATA ACL:
deny
message = We do not accept ".$found_extension" attachments here.
demime = bat:btm:cmd:com:cpl:dll:exe:lnk:msi:pif:prf:reg:scr:vbs:url
If, on the other hand, you want to remove attachments, but still forward
the remainder of the message, then you might have to do so
* either by piping the mail to an external program (e.g. "procmail")
as the default "transport" (that program would also have to
perform the delivery),
* or by launching an external filter program via the
"transport_filter" option (that program would simply print the
modified message on standard output; Exim would proceed with the
delivery at that point).
In either case, the logic for stripping attachments out of messages
would probably be best handled via "procmail" or a similar program, not
by Exim.

Ditto.
