@sindarina Problem is just that even I as Senior Linux Admin haven't heard of #JAMP nor any application that supports it.

OFC that's a #ChickenAndEggProblem: Noone's gonna implement it cuz "#IMAP & #SMTP are good enough" and "noone demands JAMP support".

OFC doing #eMail like some #JSON query is lean, and I don't doubt it.
