We have a shopping cart system that sends encrypted sale order e-mails using GNUpg... when we receive the notifications in Outlook we decrypt them with PGP.
We recently changed the system over to send HTML based e-mail instead of plain text... we had to do this to be able to pull some things from the shopping cart database (bill name) into the subject of the e-mail.
Now PGP Desktop won't decrypt the messages. It says "No PGP Information found", though you can quite easily see that the message is encrypted.
This has happened on 2 computers. The keys are installed correctly and the two computers still decrypt the earlier messages that were sent in plain text.
Whats causing this?
