i am currently doing a migration from SBS 2003 to SBS 2011, everything is going well however i am trying to move the public folders to the new server, i have asked to move all replicas however there is a public folder backfill request stuck in the smtp queue with error primary target ip address responded with 451 5.7.3 delivery type SmtpRelayToTiRg
i have checked the permissions on the default connector and made sure anonymous access, exchange users, exchange servers and legacy servers are allowed, in authentication TLS, basic exchange server auth and integrated windows are selected.
i have created a new connector with the same settings and told it to recieve mail from the sbs2003 server IP
i cannot seem to get it to work, any ideas???
thanks in advance
