  I was checking through yesterday's logs and ran across a SMTP chameleon overflow, which is unusual for us. The logs are from a machine running DNS and acting as our mail server. 

  The arachNIDs database says its unlikely the ip address was spoofed so I checked and it belongs to cheetahmail.com. Has anyone experienced anything similar and, if so, what did you do about it? 

  In any case, here are the relevant lines from the log file:

Jun  7 16:27:05 chia snort: SMTP chameleon overflow: ->
Jun  7 16:27:05 chia named[517]: "optonline.net IN MX" points to a CNAME (mail-relay.optonline.net)
Jun  7 16:27:05 chia named[517]: "optonline.net IN MX" points to a CNAME (mail-hub.optonline.net)

  Thanks for the help.
