[cobalt-users] What is a NOQUEUE connection?

["Jay Fesco" <jay@xxxxxxxxxxxx>]

I apologize for the lame question in advance...


I've started seeing this message repeatedly in the maillog on my Raq3:

sendmail[8423]: NOQUEUE: Null connection from mail.ombramarketing.com
[216.34.74.50]

I have no idea who 'ombramarketing' is - they have nothing to do with my
company.

I don't have open relaying turned on for this server, and we don't allow any
of our users to use the Raq3 for SMTP.  I see this message for 127.0.0.1
frequently, but I assume that's just the Raq talking to itself.  What's the
implication when an actual external mail server is shown?

Thanks
