I implement Domino 7.0.2 server on Windows 2003 R2 .
All users use Domino by DWA ( WebAccess ) .
2 month passed , suddenly  Mr. X  could not send e-mail to external internet user .  A.B.C@xxx.yyy.com.
Message is " no route found to domain  xxxxxx.yyy.com  Check DNS configuration ".

But other employee Mr. Y can send e-mail to  A.B.C@xxx.yyy.com from DWA .
( He has the Notes account on the same Domino server )

And another employee Mr.Z  can send e-mail to O.P.Q@xxx.yyy.com from DWA.

Is this  personal setting problem ?
What should I check ?

I appreciate advice.

A few questions:
- you have xxxxx.yyy.com and xxx.yy.com; I suppose you're not talking about two different domains?
- is Mr. X still with the same company?
- what's in the server's log database, around the time the problem mail was sent and the answer received?
- see both the Miscellaneous section and the Mail Routing section in the log database
- xxx.yyy.com is not by any chance Yahoo??

- Sorry , same domain   "no route found to domain  xxx.yyy.com  Check DNS configuration  "
- Mr. X  still work in the same office.  
- I checked server log " Mail Routing Events " .

  %year / month / date  time%   No route found to domain xxx.yyy.com  Check DNS configuration
                                                  Router: Message 0027D6AA.  0027D22B delivered to Mr.X
     
   Is there any other server log I should check ?
- I also checked Miscellaneous Events .  But no record about this.
- xxx.yyy.com is customer's e-mail address . So I cannot write it here.. Sorry..

Did this happen only once, or does your user still have this problem? It could be a temporary network problem in your company. If it's all on the same server, this doesn't seem logical to me. Did the user try to send the message again, after one of the other users successfully sent a message to Mr. X ??

I would also check that spelling of the domain is correct.

Most errors of this type are spelling issues, spaces in SMTP names, etc.

I hope this helps !

Several times in this week.  Mr.X only has this problem. Other employee can send e-mail to the same domain @xxx.yyy.com .  
At first, I also thought it might be temporary network problem . DNS or e-mail server .
The same customer e-mail server ( same ip address in this week ).
Yes, last week, Mr.x fail to send e-mail and other employee can transfer e-mail to the same e-mail account . It was during 10 min.

>I would also check that spelling of the domain is correct.
Yes, I also thought, too.  
But this case doesn't match.  I also checked .

Is there any other point to be checked ?

Just to describe the problem in pseudo-code:
- if A sends to X the message bounces
- if B sends to Y (colleague of X) the message passes

Two options come to mind:
1) ask B to send a mail to X
If the recipient is the same most of the destination path that's taken by the e-mail is the same. If B's mail arrives, the problem is most likely with your user A. If it doesn't, I'd look for problems with X.

2) ask A to send a mail to Y
Similar story: if the mail arrives, the problems is with X. If the mail bounces, check A's system.

1) Mr. X may have firewall issues or a Bad Host file that is messing with his DNS

or

2) Bad DNS server in general.

I would compare

ipconfig /all  from a DOS box, with MR X, and a user who has no issues.

Check the DNS servers and anything else that could be relevant.

I hope this helps !
