Hi, Recently I found that when I am sending a mail internally to my organisation mails asking for delivery receipt I found that the delivery receipt is coming from the actual user not from the System Administrator which usually ituse be. Has anyone idea about this case why this happens??? I have Exchange 2003 SP2

Hi,What's the name of the actual user?Please open ADUC, expand Users, find the user and right click it, select Properties, in the E-mail Addresses tab, check if you have secondary smtp address =postmaster@domain.com (where domain.com is the organization's default domain name).If have, please delete it and force the AD replication.After that, please check this issue.ThanksAllen

I checked ADUC, this user from whom I got the delivery receipt as himself has only one primary email address. Any idea???
