[msmtp-users] Schedule mail delivery

["Se Kasi" <popsch@...135...>]

Hi,

Does anyone see an easy and mail client independent way to implement a feature in msmtp to send emails only after a certain timestamp/date has been passed? Boomerang has this nice feature for gmail that you can write, for instance, birthday greeting emails earily and then schedule them to be delivered on specific days. It might be doable a special header in the email (e.g., X-SCHEDULE: 2016-07-04), and have msmtp-runqueue.sh be aware of this, however, there might be better ways.

Any suggestions?
