We have a need to encrypt an email generated from a PHP script. And the recipient needs to be able to decrypt the message from within MS Outlook. We're currently using Tectite's FormMail encoder/decoder. But the decoder is a separate Windows application and not as convenient to use.

Thanks,

Well there is a way, I just need to know more details about the situation. Like where is the email from, a free email company like yahoo or hotmail, or one of your own like lee @ yourdomain.com. Esentially where is Outlook pulling this mail from? Post back with that information and I would love to help.

The messages are created from our own PHP script/application. As the web user performs certain actions, they're automatically emailed confirmation messages or messages are sent to site owner. One of those message sent to the site owner needs to be encrypted because of the data included.

Well what you could do is create a email parser that the owners emails will be forwarded to first. AS LONG AS the owners email is not controlled by someone else such as hotmail etc. Then what you could do is have the script that sends out the emails encode the data and send it to the parser the parser decodes that script and then dumps it into the email. Still theres no 100% way to encrypt email throughout the whole transmission. You could always use an ssl and such to improve the security.

PGP isn't foolproof, but it's better than sending in plain text...

Does Outlook support PGP encrypted mail out of the box? IE, without third party apps..

I do not think so but again... I use Thunderbird so I really cannot vouch for Outlook.

No but there are several free plugins available that integrate right into outlook for a transparent encryption/decryption.

I think the OP is after a method that doesn't require a third party app or plugin.

What we have is a VPN that you have to be on to access the internal company IMAP/SMTP servers. So I've never had to look into making email secure.

Laryan, if you're hosting your own mail servers perhaps TLS encryption would be a better idea?
