[SLUG] OT - sendmail processes

[David <david@xxxxxxxxxxxxx>]

I'm getting a huge number of "NOQUEUE: no connection" messages on my
sendmail log.

Corresponding to those there are lots of processes that look like this:

[root@mail log]# ps ax | grep sendmail
  486 ?        S      0:21 sendmail: accepting connections on port 25
32559 ?        S      0:00 sendmail: startup with f244.law12.hotmail.com

When I did this particular ps, there were 14 of these processes, each
corresponding to a NOQUEUE log thus:

 sendmail[32559]:  NOQUEUE: Null connection from f244.law12.hotmail.com
[64.4.19.244]

Should I be worried? The server doesn't appear to be open relay. I've
tested it using http://www.abuse.net/relay.html
The processes seem to persist for some time. I can't find any sign of
legitimate mail from these hosts.

They are mostly hotmail or sydhosmtp01.westfield.com.au 

[root@mail log]# grep sydhosmtp01.westfield.com.au maillog | wc -l
    322
[root@mail log]#
