A local relay would help here or a configuration option for which relays can save drafts. I don't think spies would care how many encrypted drafts you have.

"Absolutely, having a local relay or configurable options for saving drafts securely would definitely enhance privacy and security. It's always better to be safe than sorry when it comes to protecting sensitive information. Thanks for bringing this up!"
