sendmail and pgp


Good morning, all!

I have a new project that's been slapped on my plate. I need to determine if there's a plug-in for sendmail to recognize a pgp-encrypted message and either flag it for processing or decrypt it prior to sending it off to our custom mailer.

So far, what I've seen leads me to say 'no,' but I'll cover and ask the populace that knows much more than I do about such things.

It's plain text and sendmail decrypt? I don't think there is a plug-in for that.

I could be wrong. I installed Windows once.

Bit of a confusing question...can you elaborate on what you mean, and what the flow of what you're trying to do is?? Based on the question, wouldn't everyone then have to load their PGP keys on ONE mail server, so that sendmail could decrypt them? Because unless they did, how would the mail server be able to prompt the user to enter a key/passphrase to decrypt it? And if you're going to decrypt it anyway to send it off via email, wouldn't it make more sense to not encrypt the message in the first place, since you're going to just shovel it out decrypted?

And what custom mailer are you using now, and how does it fit in with sendmail??

A PGP plug-in would make more sense for the mail-client. They're already around for Thunderbird, Kmail, and Evolution, and probably for other mail clients too.

Up date on PGP and sendmail

OK - some developments.

The customer is looking for assurance that data-at-rest is encrypted. The mail channel is already secured.

No worries, then......

Thanks to all!
