I'm trying to setup rt 4.4.1 to send s/mime signed email. After some fussing around and figuring out that openssl couldn't handle the full chain of certificates in the pem file it generated itself, I got RT to send signed messages, however Thunderbird complains that they got modified after signing and shows an alert on them. Has anyone else got this working?
