What filter should I use on my Email Security Gateway for a Zimbra LDAP server?

Solution #00003892

Scope:
This solution applies to all models of the Barracuda Spam Firewall, all firmware versions.

Answer:
The Zimbra LDAP server directory scheme manages aliasing different than other LDAP servers. The following filter should work effectively, where "<YOURDOMAIN>" should be in the form "yourdomain.com":

(|(mail=${recipient_local_part}@<YOURDOMAIN>)(mail=${recipient_email}))

Use this filter for alias domain:

(|(mail=${recipient_local_part}@<YOURDOMAIN>)(uid=${recipient_local_part}@<YOURDOMAIN>))
