[cobalt-users] Sendmail errors showing up on logs

[chae <chae@xxxxxxxxxxxx>]

Hi Yah,

Over the last few days I've been noticing the following show up in the 
logs, but it's not every hour so it's not a consistent problem.
The gethostbyaddr(xxx.xxx.79.217) is some of the IP numbers we have on the 
server
The to=xxxxxx@xxxxxx is the email address root sends all server 
messages/logs to

The problem only seems to be with root sending to this email address, then 
the next time it's okay, if I send a standard email through the server to 
the address no problem. I've rebooted to server thinking it might be the 
"Upgrade" memory problem with the RAQ3's but it still happens after the 
reboot. Sometimes it'll only show an error for some of the IP's next time 
it shows for all of them.

Anyone know what's causing this and how to resolve it?

Many thanks in advance

Chae
