> Jun 25 20:22:54 rolf14 dovecot: lda(rolf): Error: setegid(privileged) failed: Operation not permitted
Manual page "man 2 setegid" states that
setegid() sets the effective group ID of the calling process. Unprivi-
leged user processes may only set the effective group ID to the real
group ID, the effective group ID or the saved set-group-ID.
Your "postfix" user is a member of group "mail", but "mail" which you
configured as "mail_privileged_group = vmail" is neither the primary
group of user "postfix", nor is it the effective group id of the
calling postfix process.
Therefore you might get the error as documented in the manpage setegid(2):
The calling process is not privileged (Linux: does not have the
CAP_SETUID capability in the case of seteuid(), or the CAP_SET-
GID capability in the case of setegid()) and euid (respectively,
egid) is not the real user (group) ID, the effective user
(group) ID, or the saved set-user-ID (saved set-group-ID).
