S/Mime : Can we force encryption to be used with specific email addresses?

My hunch is that there isn’t a feature to do that right now – I don’t see anything when I pull up a contact sheet for a specific email address. For our organization, I’d love to find a way to force encryption to be used for any interoffice emails as our offices are in various countries, but emails destined for people outside would be unencrypted (or perhaps just signed)… Just thought I’d ask… thanks!

Yes, this is possible.

To send someone an encrypted message you need the recipient’s public key. So only import public keys for those you want to send encrypted messages to.

Great! Thanks for that! Much appreciated!
