Stopping onslaught of NOQUEUE messages
Feb 5 09:32:36 hpsym sendmail[523]: NOQUEUE: Null connection from [10.64.116.10
0]
I just want them stopped. How do I clear out whatever is causing it?

Re: Stopping onslaught of NOQUEUE messages
# mailq -v
Mail Queue (1 request)
--Q-ID-- --Size-- -Priority- ---Q-Time--- -----------Sender/Recipient-----------
PAA09845 5 3360147+Feb 4 15:50 root
(Deferred: Connection refused by abc.xyz.com.)
I think all I need to do is remove this request from the queue. How do I do that?

Re: Stopping onslaught of NOQUEUE messages
Try nslookup with the ip address shown in the syslog file.
This error is due to lack of standards SMTP commands from the client like, MAIL, EXPN,VRFY
Also try to do telnet
and see if it gives you Null connection error

Re: Stopping onslaught of NOQUEUE messages
Using /etc/hosts on: hpsym
looking up FILES
Name: 3comswt
Address: 10.64.116.10
It is our network switch.
# telnet 10.64.116.10 25
Trying...
telnet: Unable to connect to remote host: Connection refused

Re: Stopping onslaught of NOQUEUE messages
# nslookup
> set type=mx
> [enter your domain]
you will get output similar to this:
xxx.com
origin = xyz.xxx.com
mail addr = root.xyz.xxx.com
serial = 10001
refresh = 10800 (3 hours)
retry = 3600 (1 hour)
expire = 3600000 (41 days 16 hours)
minimum ttl = 2592000 (30 days)
> exit (to exit nslookup)
you can then look in the sendmail.cf file for the DS entry, and change it to the xyz.xxx.com server from above and retest you mail process.
