We have customer facing servers on the public internet that use our internal Exchange 2010 server for relaying. I have an issue where some recipients are not getting the emails because certain ISPs are blocking the messages. They are being blocked
because the email appears to be coming from
recipient@PubicServer.domain.com. This is a issue with out web applications code. The ISPs blocking are saying PublicServer.domain.com is not a valid sending domain so they block it. Rather then waiting for our developers to fix the App code, is there a
way in Exchange 2010 to take the relayed email and change it form PublicServer.domain.com to domain.com? Thanks!
