Dear members, All my mailboxes (Qty -70) are hosted in USA EMAIL SERVER. I am having MS Exchange Server 2003 standard edition in production environment having 30 Mailboxex, I am pulling 30 mailboxes using GFI Mailessentials which installed on MS EXCHANGE SERVER 2003. Also it is a parent Domain. Recently i have created Child domain in which i have installed MS Exchange Server 2007 within the parent organizaiton itself successully. I have installed GFI Mailessentials on MS EXCHANGE SERVER 2007 in order to pull mailboxes from USA MAIL SERVER. I have created the routing group connector to transport the email between MS EXCHANGE 2003 TO 2007 and working fine. Problem coming when any user send an email from exchange server to email-ID which is present only in USA EMAIL SERVER is not reaching. To solve the problem from the MS Exchange server 2007 ->Organization configuration ->Accepted Domain, IF i configure accepted domain as Internal relay domain, Immediately mails are blocking in exchange server 2003 and queue is becoming more and more. Please help me how to solve the problem. Thank you,

Hi, Kindly confirm which mail are piling up, i meant which queue 2003 to 2007 or internet mail, since in case we install a exchange 2007 with 2003 already there it will make a connector automatically, also are there error in event logs?? Ripu Daman Mina | MCSE 2003 & MCSA Messaging
