This has came up in the past:

https://dovecot.org/pipermail/dovecot/2020-February/thread.html#118206

I ended up developing my own system based on forwarding all emails to a program
(from which I back-up as they come in.)

I am hoping if disaster and/or misfortune were to strike my server, I could
simply cat >> back all those files in order (or not come to think of it)
in the /var/mail/<username> (or somewhere even better fit in Postfix.)


I am not interested in saving the state of the mailbox as much as all the mails
that ever come in (or go out.)


Kindest regards,
