for your private mails, creating a tunnel on Microsoft Exchange Server [if you are using Outlook, then you are one of those] and all of your mails can be viewed.

The other mail servers are not an exception ... So if it is work related, no issues ... If it is something else ... sorry but your mail is under the network administrator surveillance :)

I'm not of that type as I'm concerned only with the implementation, the rest goes to the IT guy handling it in that company.

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
