   Can binary data crashes sendmail?

Probably not sendmail, no. (Although, binary data might be sent with, for
example a buffer overflow exploit to hack the system.) Raw binary data,
however, can crash mail clients that don't know how to deal with it.

   And, is there a way to remove mail that contains binary data?

Yes, but it requires modifying sendmail's configuration file. If you're
using the m4 macro package to build sendmail configuration file, add the
following directive to reject messages with 8-bit data that does not
include a MIME header:

        define(`confEIGHT_BIT_MODE', `strict')

Hope this helps.
