How to destroy these mails
Thanks for the information
But in that way anonymous mails will choke our server. On one of my server i am getting approx 2500 anonymous mails per day. Please suggest me any solution. Can i detect these kind of mails and later on destroy them. Cant we prevent it by using two different servers for sending and receiving with different domain name. If its possible then please give me some kind of hint on how to do this.
