Hmm.
MXToolbox reports that it takes 6 seconds for my server to respond to
SMTP connections.
spamdyke's 'greeting-delay-secs' is set to 6 seconds.
Well, there's a coincidence. ;-)
Thanks, Eric -- should have thought of that.
Anyone have any intuitions about how effective greeting-delay is as an
anti-spam tactic, and whether it has any impact on real mail?

If you have spamdyke installed it may have a timer

I'm testing a newly-built mail server, and the tool at:
https://mxtoolbox.com/SuperTool.aspx
reports very slow connection and transaction times (approx. 6 seconds
and 8 seconds respectively). The server is on a reasonably powerful
and very lightly-loaded VM.
Are these times typical? (I notice that my existing server is
similarly slow). Does qmailtoaster tarpit incoming connections as an
anti-spam measure? Or does this indicate a possible problem somewhere
that I ought to fix?
Thanks,
