Hi Pooja,

Please check what the services: 25 stand for.

Also check with the admin team whether all the ports are opened.

It seems to be some http port issue.

Hi Pooja,


this problem come occasionally not reguarlly.

As the issue comes occasionally,than the issue could relates with SMTP relaying at Mail server end.Kindly involve Mail Server admin and share result for command

telnet <SMTP Host> 25

Also for confirmation check the issues if any at mail server end at the same time when you faced the Message 816 in SOST.

Dear Gaurav,

Its show

Status Text (Messege XS816)

Message cannot be transferred to node SMTP

connection error (final)

When we click on Long Text , It give below messege

Message cannot be transferred to node SMTP due to connection error (final)

Message no. XS816

Diagnosis

Due to a technical fault, the system could not set up a connection to the RFC destination 192.168.11.235: 25. Therefore, the message could not be transferred to node SMTP.

System Response

The system was unable to transfer the message.

Additional information of the node used (in the system language of the node):
Check port and mail server for SMTP nodes

Procedure

Check the connection from SAP system to node SMTP. Perhaps the node is not assigned to the correct RFC destination. If so, correct this in Customizing.
Otherwise use RFC destination management to check the RFC connection to destination 192.168.11.235: 25.
If R/3 is in productive operation, it is advisable to reroute provisionally to another node.
You should therefore notify your system administrator.

2) Email address is maintained in SU01 for the user whose name appears under Sender.

3) SMTP relaying is enabled on the mail server for the SAP server from which emails needs to flow

4) Correct SMTP server is maintained in SCOT configuration

Dear Deepak ,

In this SMTP Service is already activate in SMICM .

We have given email ID in User ID via  SU01.

SMTP  relay is already enable that y we are sending mostly mails.

But some SAP mails give error occasionally not all mails give error.

Why some mails stuck with error code 816
