Hi zhang,

We added a few domains in ldap attribute "listAllowedUser" for a maling list. Also we restricted only moderators to send email to this list. However when a user from the listed domains sends an email to this mailing list, the mails are rejected.Please find the log below

Please look into this and update .

Note: I see that allowed_senders is empty in below lines.. please check

   elif policy in ['membersonly', 'allowedonly', 'membersandmoderatorsonly']:
        allowed_senders = recipient_ldif.get('listAllowedUser', [])
        if policy == 'allowedonly':
            if sender in allowed_senders:
                return 'DUNNO (Allowed explicitly)'
            logging.debug('Sender is not explicitly allowed, query user aliases and alias domains.')

Hi Soundar,

Could you please try below patch for plugin: plugins/ldap_maillist_access_policy.py? Also, could you please show me LDIF data of this mail list account? Looks like there's some conflict in the log, i need the LDIF data to verify it.

listAllowedUser: gmail.com

Strange, the iRedAPD log says "Allowed subdomains: gmail.com", it should be "Allowed domains", not "subdomains".
