While going tru the smtpd_main.log I came across this statement:
Warning: ACL "warn" statement skipped: condition test deferred: failed to bind the LDAP connection to server X.X.X.X:389 - LDAP error 49: Invalid credentials
Its followed by "Accepted Upstream host" and "new mail queued, add to inqueue".
As inbound email is delivered and there is nothing showing in the log viewer, a user would never notice it tru the webadmin GUI.
Recipient Validation is currently set to AD but judging from this entry in the smtpd_main.log it has a bug. The credentials are correct, they test OK and are also used when users logon with SSL VPN and OTP.
I tested it and the XG will not reject recipients that do not exist locally.
