Ironport not checking the correct Address book

[charlespq1]

I have an issue today because Ironport (Relay)check the address book to forward emails from any system within Domino.All queries for users @domain.com are provided and search by Domino.

Actual scenario

eCRM  - Ironport  - Notes - Google

I want to remove that Domino and make sure that when the internal systems send email via Relay to Ironport this queries for recipients should get by Google and not by Domino.

Proposal 

eCRM - Ironport - Google

Our mail system is Google now and I want to any single query from Ironport to identify user should made to google and not other ldap server or instance.

Thanks

Hello Charles,

Correct me if i'm wrong but you would like google to do the recipient validation and not your ESA device from LDAP checks or so?

If so you may need to use SMTP call-ahead feature.

When you configure your Email Security appliance for SMTP Call ahead recipient validation, the Email Security appliance suspends the SMTP conversation with the sending MTA while it “calls ahead" to the SMTP server to verify the recipient. When the appliance queries the SMTP server, it returns the SMTP server’s response to the Email Security appliance. The Email Security appliance resumes the SMTP conversation and sends a response to the sending MTA, allowing the conversation to continue or dropping the connection based on the SMTP server response (and settings you configure in the SMTP Call-Ahead profile).

The setup and information on this feature can be seen in your GUI > Help and Support > Online Help and search for SMTP call-ahead.

Regards,

Matthew
