This plugin tries to validate recipients against an LDAP server. This will help in replacing an existing qmail-ldap installation with Haraka.
The plugin assumes simple qmail-ldap style LDAP records. It is completely
configurable using the config/rcpt_to.ldap.ini file.
The logic that is followed is:
-
Check if the recipient is for a local domain (ie. check if the domaiin is present in
host_list) -
Check if the recipient is already whitelisted
-
Run an LDAP search to see if the recipient can be found in LDAP.
