[cobalt-developers] Strange errors in mail log

["Paul Miller" <paul@xxxxxxxxxxxx>]

My Qube has recently been a target of spammers.  The problem was due to my
ignorance.  I enabled web-caching which caused an open-relay for spammers on
port 3128. I disabled the port using the web interface and the problem still
existed.   I had to manually kill processes before it was truly disabled and
the open-relay problem ended.

*Sigh*

Monitoring the mail logs like a hawk.  I'm consistently seeing these errors
every 15minutes or so.  Any information would be greatly appreciated.
