I have the following scenario:
- serverA = RHEL5 using Sendmail
- serverB = RHEL6 using Postfix
- serverC = RHEL6 using Postfix
- gwsmtp = relayhost
- example.com = domain name
As we are migrating from sendmail to postfix we get some unable to relay errors.
To explain in detail:
- From serverA to serverB I can send an email with no problem
- From serverA to serverC I can send an email with no problem
- From serverB to ServerA I can not send an email
- From serverB to serverC I can not send an email
Sending an email from serverB to serverA I get the following bounce message

We try to have the same configuration in postfix as we have in sendmail. Any help would be greatly appreciated.
