Hi all
I have a issue having disk space full due to alot of files inside /var/spool/clientmqueue. There are approximately about 90000 queue messages. I cleaned up all the queue messages in clientmqueue already and managed to check one of the queue messages.
below is the content of the message

I suspected the system trying to send email to root and rejected. It was queue and kept sending until the disk space is fully utilized with queue messages.
I would like to know where the problem is and please guide me along to troubleshoot.
First, I suspect it was due to the address "root" because it says..
----- The following addresses had permanent fatal errors -----
root
(reason: 550 5.0.0 Access denied)
(expanded from: root)
Another thing I could not figure out is message subject...
Subject: Port Denial noted sendmail-D10203
D10203 is the hostname of the server.
Pls advise me on troubleshooting and fixing.
Currently I cleaned up all teh queuemessages from /var/spool/clientmqueue. I am not sure it will come back again after some days.
Thanks in advance, indeed.
