I've been reading quite a bit of discussions, the manual and a few often linked posts about mail-crypt-plugin, but most of them seem to assume a sql db backing. But if you are using a passwd file userdb, is it possible to make the per-user-key mode of the mail-crypt-plugin work?
I like the trick of passing in the key via an extra calculated/virtual column in the query (even allows for hashing the password for example). But I cannot see how this can work with the passwd backing?
Any pointers would be appreciated.
Kind regards, Davy
(Why so focussed on passwd files? I'm using the docker-mailserver setup that takes care of a lot of messy setup, so I rather not redo that just so that I can switch to a db for storing the user details of maybe 2 to 3 users)
