Again, this is possible, but only remotely so. Millions of e-mails pass through the Internet daily. 2.1 billion e-mail messages are sent daily by U.S. users. Unless you are doing so from your place of employment, interception of your e-mail by an unauthorized user appears to be an incredibly small risk. All e-mail based risks can be virtually eliminated through the use of readily available technology.
Encryption is available for most newer e-mail clients.
As a test, a psychiatrist colleague of mine and myself wanted to see whether we could easily use encryption in an e-mail to one another. We both had encryption technology installed in our e-mail programs already, so it was just a matter of registering our public keys and sending the message. This was a virtually painless process we worked out in just a message or two. Encryption is a recommended technology which should be utilized when conducting online therapeutic interventions. For instance, if you are emotionally distraught, the additional steps needed to read and send encrypted messages may simply be too much hassle.
