Send Encrypted Mail

I have a script that runs hourly and checks the syslog for "Authentication Failed" messages. If any are found, I send an email to all the people in our help desk to notify them that there is a problem with some user accounts. The extracted user info is send in the body of the email. These emails are from a HP 11.23 Unix Server thru our Microsoft Exchange Server. Unfortunately, I need to send this email encrypted because of Internal Security Controls (DOD). Normally with Exchange, you can click on the "Encrypt Message contents and Attachments". How can I do this with Mailx? Can I use uuencode on the Unix side? How would the Windows user decode it?

Re: Send Encrypted Mail


You can encrypt mail attachments with the crypt system call.

Internet Express (search for it)
Pick the one for your OS.
Then choose the PGP software, install it and you have a full encryption system.

Whoever reads the mail will need PGP configured to work with their mail reader.
