"... deep down ... should be ..."
These words do not sound very encouraging.

The purpose of quit() is unrelated to whether the mail was or was not  
sent.  The purpose is to gracefully send a QUIT to SMTP server and  
then _close_ the socket.

Are we absolutely sure that the socket gets closed here and that we  
are not leaking sockets (i.e., file handles) here?

If we are not, we should not pass on the exception.
Moreover, we should not pass on _every_ exception.
