Ldap with 2 email addresses (for delivery of spam while filtering it out)

Hello! We have implemented a email security appliance from sonicwall and we use ldap to communicate between the device and the Domino Server. I have a person who has 2 email addresses and I was wondering how to get his person document to store two email addresses and for ldap to understand that.

Do anyone have suggestions to get this accomplished?

Thanks,

Jamie
