smarthost random numbers before the email address
Posted on 2008-06-17
We are using Exchange 2007 SP1 as a smarthost for email coming from our Windows 2003 web server's standard SMTP engine. Some, but not all of the email coming from two different web servers have random numbers (usually one or two digits) before the email address. The from addresses on these emails are real email addresses on our email server, but they don't authenticate with the smarthost as it's setup to be anonymous. All of the email addresses being sent to are to recepients outside of our organization. I've been looking for a solution to this for quite some time now, but can't find anything. Any ideas would be appreciated.
