check_smtp socket timeout problem

[Lane, Jim]

It now seems the problem must have been with sendmail on the monitored
system. I was modifying debug options and restarting the sendmail daemon
in hopes of getting useful info. After a couple of restarts all of a
sudden the plug-in started to work properly. Beats me!

Are you using the latest version of the plugins? There was a bug a long
time ago that prevented the plugin from successfully quitting in some
circumstances. If you're familiar with the usage of strace or truss, the
output around where the plugin sends the QUIT command might be
informative.
