I received this e-mail today. Apparently, one of my servers can be used to
relay spam even though both are secured so they individually can't relay
spam. However, since one sends its e-mail to the other then spam can be
relayed, if I understand the message. How can I stop this? I am using
sendmail 8.9.3.
>ORBS (see http://www.orbs.org/) has discovered an open SMTP relay

>into this open relay, 198.206.243.x forwards the relayed message, for
>whatever reason, to your server at 198.206.243.y, which then delivers

>The end effect is that 198.206.243.y may be acting as a spam delivery agent,
