Hello, Could anyone please correct me if I misunderstand? 1. To reject invalid recipient, the recipient validation has to be enabled. Is it possible to use synchronization instead of recipient validation? 2. To drop invalid recipient, the synchronization has to be enabled. 3. In case of reject invalid recipient, what is happen if SBG can not contact LDAP server? Will every SMTP connection be dropped? Thanks, Nitass

Hey Nitass,

So I can understand this is a little confusing. Recipient Validation is actually an option available "instead of" synchronization. Recipient Validation does a lookup at the time of validating the recipient instead of keeping a synchronized database of entries to querry. And actually may be a better option for you depending on your needs.

To answer your second question, you can use either synchronization or recipient validation for dropping of invalid recipients.

And lastly, we will keep a listing of entries in either case to continue to have a proper listing of users. So in the worst case, you could just turn off dropping of invalid recipients if your LDAP server goes down. But I don't believe it will drop all mail.

Hope this helps!

Just some more comments:

1. A recipient validation source is required to reject messages to invalid recipients, if using LDAP Synchronization then you need to choose the option to drop messages to invalid recipients which actually accepts messages to invalid recipients, scans them and then silently drops the message instead of trying to deliver to a non existent recipient.

 

2. Answered above in 1.

 

3. If the LDAP server can't be reached when rejecting to invalid recipients using a Recipient Validation source a tempoary error is issues to the connecting server telling it to try again later.
