Summary: SMTPDirect.py can hang indefinitely

Initial Comment:
SMTPDirect.py connects to an SMTPHOST that may
terminate its TCP connection incorrectly. This will
result in the OutgoingRunners hanging, especially if
the SMTPHOST still accepts connections.

This is a patch that wraps the SMTP transcaction in an
alarm() to prevent OutgoingRunners from hanging
indefinitely.
