I am using RH 9.0 and keep getting two unknown users in the Sendmail root mail
message.
user_unknown1@mydomain.com: 12 times
user_unknown2@mydomain.com: 10 times
Sendmail end---------------------------
does this mean someone is relaying or just trying to send mail to non
existent users?
What programs could I use to give a clearer picture of my mail and network?
Thanks for your help.
