I am the network administrator where I work.
When users are hired here they sign a long contract of acceptible internet/email/computer usage which basically says you can only use the stuff here for work related purposes and that all users can be monitored to see if they are infringing the contract they signed...yadda yadda...Basically giving me the right to read ppls emails and monitor web activity and such. It should be noted that I have never exercised this right and the only time I open someones mailbox is when the user is having problems and they ask me to check something out. Web access is monitored on an anonymous basis and I block pages using websense that I feel are inappropriate. Spam/viruses are blocked with Trend Micro IMSS and I occasionally monitor what is blocked for false positives but the contents of emails are never reported to management or anyone else for that matter.
Recently a user was caught (not by me, probably a customer or someone looking over his shoulder) using his email account for inappropriate and non-business related purposes and it was reported to management. I got notification from management to suspend his email account so I exmerged a back-up of it and then deleted his mailbox. That was yesterday. Today, people are walking by my office giving me dirty looks and making comments like "read any good emails lately?" My guess is they think I am responsible for ratting him out.
I consider myself a quiet but friendly guy and now I am seen as the jerk computer guy who reads everyones emails when this is far from the truth.
How have you other admins out there handled this situation or how would you?
