It appears that your request tracker is only connecting, but not sending 
any commands to your sendmail once connected as the message is implying. 
 I found the following on www.sendmail.org I think should be helpful...


    Subject: Q4.18 -- What does "|NOQUEUE: Null connection from ...|" mean?

Date: February 24, 2000
Updated: March 12, 2000

An entry like:

NOQUEUE: Null connection from host.domain [IP.AD.DD.RESS]

in thelogfile <http://www.sendmail.org/%7Eca/email/div.html#LOGFILE> 
means that |host.domain| connected to your MTA but neither initiated 
transmission of a message (by issuing the |MAIL|command), nor used any 
of the commands that are logged separately (|EXPN/VRFY/ETRN|). Unless 
this happens very often, you can ignore this. If it happens very often, 
it's either someone playing around or it's a network problem.

Note 1: The significant part of the message isn't the |NOQUEUE|, but the 
"|Null connection from ...|". In particular,|NOQUEUE| isn't an error 
indication, but just a "place-holder" when no queue ID has been 
assigned, typically because message collection hasn't started (yet). It 
can occur in other messages too, and there too the significant part is 
what comes *after* the |NOQUEUE|.

Note 2: In 8.10, the text which led to the confusion has been changed 
to: "|... did not issue MAIL/EXPN/VRFY/ETRN during connection to ...|".
