While I do agree that it is easier to just go with an encrypted transport
for receiving mail, I also think that in reality it does not buy you very
much extra security.
If these documents are truly sensitive, then you need to use some form of
end to end encryption. If you fail to employ a solution that encrypts the
document before you send it, then you have a plain text version of the
document sitting in the spool on the mail server, and in the received mail
folders on your mail client.
Also, a solution that relies on transport layer encryption suffers from the
fact that man in the middle attacks can be used by an advisory that has
the ability to intercept the protocol and change it (if the end user does
not pay attention to the warnings that there mail client may generate)
