Sam will know better, but it looks to me as though there's something not 
quite right happening in the smtp session that results in spamdyke 
timing out.

Please use the detailed logging option:
full-log-dir=/var/log/spamdyke
(you'll need to create that directory w/ appropriate permissions)
to see where exactly the session is hanging. Post the log results here 
if the problem isn't immediately apparent.
