Hi there --
The root user on our sendmail 8.13 server appears to have its e-mail address doubled up, and this is causing the following error message to occur:
<root@hadron.mgh.harvard.edu.mgh.harvard.edu> Sender address rejected: Domain not found
ahkaplan@partners.org... Deferred: 450
What file(s) do I need to modify to correct this problem? Thanks.
