Hello,
A few of my users are getting this message when
they try to send email to a couple of domains:

The following recipient(s) could not be reached:

'kyates@afyainc.com' on 8/29/2004 4:17 AM
The destination server for this recipient
could not be found in Domain Name Service (DNS). Please
verify the email address and retry. If that fails,
contact your administrator.

<db-sbs.dbconsultinggroup.com #5.4.0>

-----
This happens only when sending to afyainc.com and
danya.com All other internal and external emails seem to
be going fine. Any suggestions? Thanks in advance,

-Abhi
