Mail flow issue Exchange 2013 RRS feed

  • Question

  • i had  exchange 2007 distrusted among 20 sites, Mail flow of 2007 Server are working fine.

    Recently i have installed 3 new Exchange 2013 server (MB and CAS role)
    site1: 1 Exchagne 2013  (MB and CAS role)
    Site2 :1 Exchagne 2013  (MB and CAS role)
    Site3: 1 Exchagne 2013  (MB and CAS role)

    I noticed that outgoing mail flow of Exchange Server 2013 always goes first to site1 and then reaches to destination site, Taking an extra hop in mailflow.

    i have already checked There are no Exchagne Cost defined No Hub site configured, Also AD Site Link Cost is 20 for all.

    Please help
