I am sorry, I seem to really have missed it.

But less? How can it report e. g. 4.5 minutes if BBSLEEP is 5 minutes?

Where do I find the numerical response code? All the display page says is

   mailgw2.itsystemsservice.de - smtp
   red Tue Aug 30 09:07:01 CEST 2005 SERVER - smtp DOWN

It is really unlikely that the smtp server is throttling because its 
machines that idle most of the time: secondary and tertiary mail 
gateways e.g. But I will have a look at that.

Thanks for your help.
