Quick synopsis:
1 in-house exchange server
accepts multiple domainname.com address (non of which referred to below is the primary domain)
mxlogic servers filter our incoming mail to us
domainsname.com hosted externally and those Name servers have correct MX records.

All was working until recent request to have domainname2.com website redirect to domainname3.com website sent to web person.

**Post**-
mail stopped(was intermittent) working to domainname2.com from external senders.
Could only get access today to update correct mxlogic records myself through hosted site.
Made change to exchange server to add primary smtp as domainame3.com but keep domainname2 working still through co name change.

Suddenly Hotmail/outlook(web mail off desktop) to @domainname2.com(original) is reporting below and almost immediately returning unable to deliver.
Gmail seems to work from cell.

Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;550-Please turn on SMTP Authentication in your mail client.
550-col004-omc1s12.hotmail.com [65.55.34.22]:62234 is not permitted to relay
550 through this server without authentication.


Ideas?  I hope I was clear enough...

Hello,

What DNS records did you update? Do the MX records for domainname2,com point to an A record that has the IP of the mxlogic servers?

When you make DNS changes, there can be a delay due to caching. If mail from Gmail is working, it is possible you just need to wait for hotmail to update your DNS in their cache.

taken care off.. the message is basically saying one of Hotmail's own servers won't allow relay.   The next day seemed fine.
