My guess is that MIME::Tools is very slow on such large messages.  Not
only do you have to increase Sendmail's timeouts, but you also have to
increase MIMEDefang's timeouts.  See the mimedefang-multiplexor(8) man
page and the "-b" option.

Policy question: Do you really want people sending 30MB e-mails?  My
server refuses anything over a megabyte.  Such large e-mails are an
inviting DoS mechanism, especially if someone knows you're using
MIMEDefang.
