hey friends, One of my friend's office they have sniffers for mail.I explain the scenario in their office there is no internet connection given to the programmers or developers whatever they have is their official mails.They can only receive and send mails through their official mail ids.Whatever they send and receive is passed through some sniffers or some filters programs if something related to the company is going out they fire that developer or programmer. What i want to know what kind of programs they are using to filter those mails.I don't know much about their setup as my friend is a software developer and he has very less knowledge about the system administration part. Can anybody tell me about those sniffers and programs for filter or checking the mail traffic. I would like to have such kind of setup in my office. Thanks & Regards Ankush
