Mails not Relaying to a Smart Host

Good Evening Team,

I am having an issue with Mails being relayed to destination server. The mails are currently being held on the Routing Mail boxes as show below

Could the issue be on my on my Routing on the Server .

My users are receiving mail though

On reviewing the Mail routing events i get below:

Apply hot fix for domino day 1

Which hot fix for Domino Day 1

Please read this article:
https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0118192

You have to install FP2 or FP3 before to apply the Interim Fix for the Critical Alert.

Hello @Ian Rotich

There is a critical alert reported on Domino Servers since 13-Dec-2024 impacting mail routing on restarting Domino Server.

Please refer below article for more details.

URL: https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0118192

Please apply 14.0FP2 and then IF2 on the Domino server to resolve the issue.
You can also apply 14.0FP3 and then IF2 on the Domino server to resolve the issue.

I hope it helps.

Regards,

Pramod

Are these emails for smart host or your users sent them to external users ?. When was your server restarted last time ?

If the server was restarted on or after 13th December, 2024. You may be hitting the issue as per critical alert KB0118192.

Looking at the screen shot it shows 4 mail.boxes so I believe the server may have not restarted in the above period. Can you check the status by issuing the below commands on the server.

Show Server

The output should show Availability Index 100 or less than 100 but not "0"

Show AI

The output should show XF column values with some numbers and not "0"

Also issue the below commands to know status of the router.

Tell Router Show.

What is the status it shows.

Thank you

Show Server

Availability Index is 100

Looks good and you are not affected by the critical routing issue as per the KB0118192. However, if you restart the Domino server then your routing will be affected and you have to install the FP3 + IF2 on Domino 14.0 (14.0 FP3 IF2). So it is recommended to apply the fix on the Domino server.

For current routing issue you can check the mail.boxes and see how long those mail are sitting the mail.box.

You can try below commands to know more.

tell router show

What it shows in the ouput ?

Enable below debug to know more details on the SMTP transaction.

Set config SMTPClientDebug=1

Tell router update config

Tell smtp update config

Route *

This should print more information on the SMTP outbound messages.

Thank you.

@Shrikant Jamkhandi Many Thanks for your valuable support and knowledge sharing.The mails are now being relayed to the host the error was at the host

tell shower router -i am getting attached results

Which commands will print more information on the SMTP outbound messages???

The tell router show command shows nothing pending, which means all is good. The mails pending were seen because it may be a temporary issue at your relay server. Now nothing to worry. However, as said earlier you need to upgrade the Domino to 14.0 FP3 IF2. Thank you.

Issuing the debug command "Set config SMTPClientDebug=1" will print the SMTP communication as below on the server console and in the consoler.log of the Domino server. Since the routing is ok now debug is not required.
