To authenticate Qmail Submssion/SMTPS against Dovecot instead of vpopmail download and compile [this] file

# wget https://raw.githubusercontent.com/qmtoaster/source/main/qldapauth.c
# dnf install openldap-devel
# g++ -o qldapauth qldapauth.cpp -lldap
# mv qldapauth /home/vpopmail/bin
# chown vpopmail:vchkpw /home/vpopmail/bin/qldapauth
# chmod 755 /home/vpopmail/bin/qldapauth

# systemctl restart dovecot

Change Submission & SMTPS run files:

#VCHKPW="/home/vpopmail/bin/vchkpw"
VCHKPW="/home/vpopmail/bin/qldapauth"

# qmailctl stop
# qmailctl start

You should be good to go.

Check for success (or failure) in /var/log/maillog, add to run file
export LDAP_HOST="192.168.1.x"
export LDAP_PORT=389
