Messaging Gateway

I need information on a policy of a Brightmail Gateway virtual appliance running the 8.0.1 software.  The Brightmail Gateway is set up to do LDAP sync for Sync and Recipient Validation to an Active Directory domain.  It is accepting messages to be relayed to a mail server.  What I am wondering what is if the domain controller that it is doing the LDAP sync with and the mail server that it is relaying messages to are offline for a while, how long will the Brightmail Gateway accept messages for that domain with the LDAP info that it has loaded?  How long will it store the messages for relay to the mail server that is down?

Thanks.

Hi Matt,

So you have an LDAP Source created for LDAP Synchroization, it also sounds like you have an LDAP source configured for Recipient Validation?

What you aren't really clear about is what your Invalid Recipient Settings are set to do, eg. are dropping messages to invalid recipients(uses LDAP Sync), or rejecting messages to invalid recipients(uses recipient validation)?

Cheers,

Kevin

It is set up as Synchronization and Recipient Validation.  It is set up for Reject invalid recipients.

Hi Matt,

If the LDAP server is down and you have set the SBG to reject messages to invalid recipients using recipient validation then the SBG will send a temporary failure to the sending SMTP server until the directory comes back online.

Good SMTP servers should keep retrying to send after receiving the temporary failure so you shouldn't lose any messages in this situation.
