about secondary MX

Wyatt Chun
Hello

If the primary MX server returns "mailbox full" error, will the delivery agent try to send message to the secondary MX?

example.de.                299     IN      MX      10 secondary.mx.
example.de.                299     IN      MX      5   primary.mx.

Thank you.
