I have an exchange user that is sending email to a few domains. When he sends out, he continually gets undeliverables from our exchange server saying:
Sent: Thursday, May 05, 2005 1:02 PM
To: User Name
Sent: Thu, 5 May 2005 12:20:08 -0400
did not reach the following recipient(s):
firstname.lastname@example.org on Thu, 5 May 2005 13:02:18 -0400
Could not deliver the message in the time limit specified. Please retry or contact your administrator.
I am wondering if the problem is as such:
In our active directory, the user name is email@example.com and the actual real email address is firstname.lastname@example.org. However, the user wanted the email@example.com as their email address. So i made an smtp address firstname.lastname@example.org, but left email@example.com as the default reply to address.
Do you think that since someone sent him email to firstname.lastname@example.org, he hit reply and it sent from j.doe.domain.com, that the recipients exchange server or other mail server blocked the mail since the reply-to address is not the same as the original address it was sent to? I am wondering if this is my problem. It seems that i only have this problem with people that have multiple smtp addresses. By default i leave the default reply-to address as their original email@example.com, and just add firstname.lastname@example.org so they can receive mail on that too.
