Mail Routing between R7 and R4.6 on NRP
I have 2 domain and i need to cross certify 2 servers from each domain to route mail b/w them. In domain A server is running version 7 and in domain B server is on 4.6 version.
Domin B server refuses to cross certify Domain A's servers safe copy and gives the error "Unsupported ID file version". hence can't route the mail between them. (BTW I tested with a safe copy from a 6.5 version server and 4.6 had no problem in accepting that)
Do we have other means to route Mails on NRP between 7 and OLDER version now?
Do you have any Idea or suggestion?
Thanks
