The ideas and specifications for PGP 9 sounded just great. But alas, this product sucks. As I have a growing demand for encrypted mailing, my idea was to set up a special email-account for encrypted communication and to have it handled by PGP automatically - meaning that any incoming mails would be decrypted and any outgoing mails would be encrypted automatically (as long as keys are known to PGP for the communications partners). This is exactly what PGP 9 promised - comfort on receiving encrypted mails and no danger to "forget" encrypting an outgoing message. But I never got this working. The product wants to control my entire mail-traffic and I was never able to focus it only on the pgp-email-account. It just won't do. So I thought, I might live up with this, give it control over all accounts and then define the rules for each accounts, so it would control those non-secret accounts but do nothing on them. And this didn't work at all too. Sometimes it would store my settings but not follow them, but in most of the cases the settings weren't even stored correctly. Again and again I found myself with messed up settings after going into the app, and if they weren't messed up, they just wouldn't work. What a frustration. My mailclient (Mailsmith) is not supported and even manually encoding/decoding in Mailsmith does not work any longer (as it did on PGP 8). For me, PGP9 is a complete and utter failure.
At least they were fair enough to provide beta-testing for free, so I encountered all the trouble before wasting money. I appreciate this and put it on the pro-side.
