Zitat von Javier Henderson <jav...@kjsl.org>:
Greetings,I am trying to configure Postfix to gracefully deal with the failure of the LDAP server it uses for alias resolution.It's working fine, using the LDAP server to resolve u...@domain.com to u...@somehost.domain.com, but if the LDAP server dies or becomes unreachable for whatever reason, Postfix replies with 5xx error codes about the user being invalid.Is there a way to configure it to return 4xx codes so the remote end tries later?
Postfix always returns 4xx when a map used for lookup is unreachable. It only replies with 5xx when the map lookup succeed with a negativ result.
Show logs from an event in question and postconf -n output. Regards Andreas
