External email flow problem   
Hi All.

current config: Exchange Server 2003, Windows 2003 STD

I'm having an issue where email sent by external parties are not getting 
delivered to our users. Nothing is on the queues. I'm able to telnet to the 
external ip address and send mails without problems. Outbound mail works ok.

I'm guessing this might be a dns issue, am I right?

Any ideas?

regards

Where are you MX record/s pointing?

Yes, check your MX Record at www.dnsstuff.com and what NDR is being fired 
back to the sender?

Re: External email flow problem   
Thanks,

Here's the NDR

This is an automatically generated Delivery Status Notification

Delivery to the following recipient failed permanently:

    oscarg@mydomain.com
Technical details of permanent failure:
PERM_FAILURE: Gmail tried to deliver your message, but it was rejected by 
the recipient domain. The error that the other server returned was: 550 550 
Requested action not taken: mailbox unavailable or not local. We recommend 
contacting the other email provider for further information about the cause 
of this error. Thanks for your continued support. (state 14)
