This has came up in the past:

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,
