iRedAPD has plugin to force mail users to change password before sending email:
sql_force_change_password_in_days: for SQL backends (MySQL, MariaDB and PostgreSQL).
ldap_force_change_password_in_days: for LDAP backends (OpenLDAP and OpenBSD built-in LDAP server
When user trying to send an email, iRedAPD will invoke this plugin to check password last change date stored in SQL/LDAP and compare it with current date. if password last change date is longer than specified days, this plugin rejects smtp session with specified message.
To enable this plugin, please list the plugin name in iRedAPD config file
plugins =. For example:
# For SQL backends plugins = [..., 'sql_force_change_password_in_days'] # For LDAP backends: plugins = [..., 'ldap_force_change_password_in_days']
There're two optional settings you can set in
# User has to change password in certain days. Default is 90 days. CHANGE_PASSWORD_DAYS = 90 # MTA will reject user's smtp session with below message. You'd better describe # why user's email was rejected and guide user to change password. CHANGE_PASSWORD_MESSAGE = 'Please change your password in webmail before sending email: https://xxx/webmail/'
Then restart iRedAPD service.
