This is a mistake !!!!
If your server is sending an "autging" mail
and the recipient server is unavailable, your server
will try 10.10.10.2 that should reject the email
and your sender will got a NDR.

Did you set a transport for domain3 ?
If slave share the same ldap data as the master,
maybe it will not understand why you setup a transport to itself.
You should define a transport per mailbox, not for all domain3
or customize your master.cf templates accordingly
