Exchange transport error

WE are running our mail trhu a mail server at our webhosting company and
pulling it down to the exchange server thru Pop Manager.

Recently got these errors in my nightly report:

1> A non-delivery report with a status code of 5.4.0 was generated for
recipient rfc822; (Message-ID
<>). Causes: This
message indicates a DNS problem or an IP address configuration problem
Solution: Check the DNS using nslookup or dnsq. Verify the IP address is in
IPv4 literal format. For more information, click

2> A non-delivery report with a status code of 5.4.1 was generated for
recipient rfc822; (Message-ID
<>).

I believe I had the PTR, MX & A records set properly, but maybe not

the url is searscrawford.com

is it a setting on my exchange server or at register.com?

I'd agree there Brian... the first NDR is generated because someone has
miss typed the email address by the look of it.. there is a
kshlawfirm.com

This could be useful for the OP:

Nothing to worry about...
