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.
