Sep 09 13:52:31 lda(test@mydomain.com): Fatal: setuid(101) failed with euid=5000(vmail): Operation not permitted (This binary should probably be called with process user set to 101 instead of 5000(vmail))
LDA must have root permissions to switch between users with different unique system UIDs. Grant Setuid Permissions on the LDA binary (this could get reset with a system or package update):
chown root:mail /usr/libexec/dovecot/dovecot-lda
