[Dovecot] Access filesystem (NFS) as some user

[Mihamina Rakotomandimby]

Manao ahoana, Hello, Bonjour,

My Dovecot server has to access the users Maildirs.
Maildirs are on a NFS mount that only a user (vmail/500) may read
and write. No one else.

How to configure Dovecot so that at least disk read-write are performed
as a "vmail" user (that I have created with the right attributes)?

Is the workaround of changing dovecot's system UID/GID a not-so-bad one?
(I am trying to see if it works, at least...)

Misaotra, Thanks, Merci.
