Now it seems to work using ldap backend to sync maildrop and dovecot info ;)
I followed wiki example and I'm using this simple convert script because I'm storing quota info in ldap using the courier format <bytes>S to use it with maildrop (through authlib) too -- quota_convert.sh #!/bin/bash if [[ -n "${QUOTA_COURIER}" ]] ; then # strip the 'S' from the stored quota value (courier format) export QUOTA=maildir:storage=`expr ${QUOTA_COURIER/S/} / 1024`:ignore=Trash fi exec /usr/libexec/dovecot/imap PS: checking for non-zero length var avoid an expr error message when dovecot starts Many thanks for the help.
