Hello Sébastian, I remember replying to a similar post on Unix Stackexchange in the past: https://unix.stackexchange.com/a/554369/85046

Dear all, I would like to be able to respond to emails quickly to have it done but defer the actual sending of the response to slow down conversations. Ideally at the moment of sending I would specify a date and time after which I am fine with the mail being sent. For example, I respond to an email on Friday afternoon but can express that I want it to be actually sent anytime after next Monday 9pm. That could be by adding a special header to the email or by responding to questions at send time, I don't mind and it's not really the usesr interface I'd like to discuss here. What I rather would like to discuss is rather whether and how this could be implemented in the MUA/MTA framework mutt belongs to. I believe that more integrated solutions like Thunderbird do have such scheduled deferred sending features, but I have no idea how this can be achieved in presence of both an MUA and an MTA because the feature seems to be at the interface between the two: there needs to be a way for the MUA to tell the MTA about the deferred sending and of course the MTA does not only need to undestand it, it also needs to actually implement it. I had a superficial look to exim4 which I use as an MTA but didn't find anything related, but perhaps my search has been too shallow. I also considered adding another MTA between mutt and Exim4 which would keep the deferred mails until the scheduled date and pass them to Exim4 only at that moment but it felt a bit a pity to have to use one dedicated software component just for that as, I assume, it would widely resemble a traditional MTA, having a lot in common with it. Any idea will be more than welcome. Best wishes, Seb.
