Waiting for DNS Availability

Hi all

I know this issue has been posted before, but I have tried all of the solutions listed with no luck.

When my users are sending external emails, most are sent immediately, however every now and again an email will just wait in the mail.box with no error status.

When I do a “tell router show queues” its says that it is # waiting for dns availability. The number waiting on dns seems to grow steadily over the day. The only way I can get rid of these emails is to a “tell router update config”. This pushes the emails out straight away and seems to sort the problem for a while.

Problem is I cannot sit and monitor the mail.box for stuck emails all day.

So far I have tried

  1. Deleting and letting the system auto create the mail.box

  2. removing any old or empty nic entries from the system registry

  3. Checked the dns connection and enetered the dns severs into the notes.ini

Also when the waiting for dns message appears I have tried resolving dns on the server and it works without problem

I’m really stuck and any help/suggestions would be appreciated

Subject: Waiting for DNS Availability

I have had the problem of no being able to send an email to a certain few domains. No smtp log instance is ever created. The email just stays in the mail.box until it expires. The following are the things I had to do to fix this. Note that I ahd done all of these in the past, but after I made sure they were all done at the same time did I see successful results.

Verified MTU, using Ping -f -l 1472 mailserverIPaddress

changed the packet size, anything over 1472 would fragment

In Notes.ini, set DNSServer=externalDNS,InternalDNS

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces

I deleted the extra interfaces (the ones that were blank or incorrect)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\nameserver

I set the nameserver to InternalDNS

Restart Task Router

I have tried all of these before, however I think they were never done at the same time

Not a solution, but I suppose you could schedule the “tell router update config” every 30 or 60 minutes, to keep mail from piling up while you’re looking for resolution.
