'no such user' sbs 2011 Exchange 2010
Hi All,
here's the issue I did a swing migration from sbs 2003 to sbs 2011. Exchange hosts 3 domains. All three domains were working for several days. I rebooted the server last night. Today I can email, from an external source, only two of the three. All accounts at the third domain get 'no such user' bounce back and yes, internal email is just fine.
ps: fyi I can't get vpn going (error 691) and have been in the network security policy but have, to my best knowledge, set all back to original settings. not sure if that could cause an issue but wanted to communicate it.
any answers?

That isn't an Exchange NDR.
Therefore it has come from something else.
Does Cloudmark answer the SMTP traffic? If so you should check that configuration, particularly if it does recipient validation.
If not, then check the DNS records to see if they point elsewhere as well.
It isn't Exchange rejecting the email.

the ext dns for the domain is hosted at register.com.
