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):

Code: [Select]

chown root:mail /usr/libexec/dovecot/dovecot-lda
chmod 4750 /usr/libexec/dovecot/dovecot-lda
postqueue -f
