[cobalt-users] Qube2 - NOQUEUE entries in Sendmail mail log

["John O'Keeffe" <john@xxxxxxxxxx>]

Hi list,

We are having great difficulty receiving mail messages from clients with
hotmail accounts.  To the hotmail clients, the messages appear to go through
fine - but our users don't receive the emails.  Emails to hotmail accounts
are fine as well as all other mail seems to come and go fine.  Occaisonally
a hotmail message will make it through, but it comes in hours after it was
originally sent (if at all).

In the mail log  (/var/log/maillog ) I can see entries like the following:

May 11 13:16:46 mail sendmail[1592]: NOQUEUE: Null connection from
f137.law9.hotmail.com [64.4.9.137]

This was the result of an attempt to email myself from a hotmail account.

Can anyone explain what is going on here and/or where to go from here?

(We're using the following hardware as well:

Netopia R3100 Router with firmware 4.6.3 (with NAT switched on)
128k ISDN connection
)

Thanks in advance
