I'm not really crazy about adding a sigalarm handler here to fix this
problem, especially because it really does appear to be caused by a bug
in your smtp server (or load balancer -- but it makes no difference from
Mailman's point of view).  OTOH, as you say, there's no (public)
exposure of the underlying socket object in the SMTP object.  Even if
there was, in newer Python's you'd have to watch out for SSLFakeSockets
which don't expose the real underlying socket.

I'm -0 on this patch.

Aside from that, it's generally a much better idea to use SourceForge
for posting patches.
