Would anyone have any thoughts on this one:
Sent out an email to a distribution list of about 500 people external to our system. I received about 120 delivery failure notices. As a test, I set up Outlook here at work so that I could access my home email account. I sent each of these 120 a test email through this account, using the same SMTP server I use from home. Same exact addresses failed. Then, I sent a test email from my personal web-based Gmail account, most of which have gone through.
Are there any settings in Exchange that I am unaware of that may have an impact on this. I have already checked, and we have a proper rDNS entry with our host. We have Exchange 2003 Server running over Windows Server 2003.
