Does smtplib lookup MX records?

I've been trying to send emails with smtplib and had a large number of
failures. Investigation seems to reveal the the smtplib module does a
simple connect passing the hostname to socket.connect without trying
to resolve the MX record.
In some cases this works where the mail server happens to have an
A-type DNS record anyway but otherwise it fails with a connection
Is this really the case?
If it is, what do I need to do to lookup the MX record myself?
(This is rather urgent now as this program was hastily written to help
a client out who's mail server has died.)
