SMTP Communication problems with Exhange and MS CRM
Posted on 2006-07-24
My Exchange server sends emails without issue, however, when sending from our MS CRM app, I get this error:
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<companyname.com #5.5.0 smtp;521-EHLO/HELO from sender xxx.xxx.xxx.xx does not map to companyname.com in DNS>
I am not sure what is going on here...
our mail server (mail.companyname.com) url is at xxx.xxx.xxx.xx, but companyname.com is not - so that is likely the issue. But how is this corrected?
