Error while sending mail from SAP???

[farkathulla_cikkanther]

Hello Friends,

     We are getting fallowing fallowing error while sending mail from SAP.

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 smtp.caribbean-airlines.com: 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 smtp.caribbean-airlines.com: 25.
If R/3 is in productive operation, it is advisable to reroute provisionally to another node.
You should therefore notify your system administrator.

we have configured SMTP in our system then tryed to send a mail, it throws an error like above.

Please help me to solve this error.

Regards,

FARKATH C

As well as make sure that your email server ( exchange server ) is configured to accept mails from your SAP system.. Speak with your exchange administrator in case if you are facing any relaying issue

Hello

Configuring the SMTP settings in SAP will not be sufficient.

You need to also configure the relay settings at the mail server side.

You probably need to ask the Mail server admin to do this.

Hi Farkathulla,

You are getting the above error because smtp server is not configured properly.

It is not allowing to send the mail to external.

You can involve the unix team in this case and they will do the needful work.

You did not read the info i sent you before..

SAP does not have the ability to use username/password authentication against your SMTP Server, because of that you need to add the IP Address of your SAP system to the "Relay Agent" of your SMTP Server.

You need to get your Exchange colleagues to do that for you.

Thanks Reyes,

telnet port is connecting successful, please find the screen short,

Mail is successfully send to same domain(a.com) mail addresses like xxx@a.com, if I send to xxx@b.com means it getting failed.

I will check with my exchange team.

Thanks&Rrgards,

If you send mails to the same domain registered in SAP then no authentication is required. If the mails going outside the domain then you need the "Relay" in place so the outgoing mails from SAP are trusted by the SMTP Server

Good Day Farkath

Have you considered checking SMTP server with a mail administrator.

Like I have mentioned before the relay settings play an important role in the transmission of the e-mails from SAP.

hi Farkathulla,

I already faced this issue and this is due to Mail host. If you have Mail/exchange server then please put that smtp in Mail host in SCOT. If you are using the smtp of ISP then put that ISP's smtp address with 25 port. IP and port number should be allowed in firewall.

Hi Farkathulla,

ping the IP from the server

if the ping successful

  Then

telnet IP 25

Kindly check and provide the status

Hi  Ashutosh Chaturvedi,

telnet is failed.

C:\Documents and Settings\tstadm.SAP2TSTSRV>telnet 25

Connecting To 25...Could not open connection to the host, on port 23: Connect failed.

What i have to do for this.

[JPReyes]

telnet 25

Nope... you need to telnet he host+port of your SMTP server from the SAP host, this is a very basic check.

telnet <SMTP_Host> <port>

Regards, Juan

[farkathulla_cikkanther]

Hi Reyes,

   C:\Documents and Settings\tstadm.SAP2TSTSRV>telnet 172.20.0.154 25

Connecting To 172.20.0.154...Could not open connection to the host, on port 25: Connect failed.

for this what i have to do?? i will check with my IT team.

please tell me if you have any idea...

Thanks

Hi Farkathulla,

Hi Farkathulla Cikkanther,

Check with your IT Team,

Port 25 is not open , it is a  firewall issue.

Hi Farkath,

Assuming this is a new connection that has not been working before:

1. from the SAP server see if you can telnet to the smtp server on port 25

2. Check out transaction SOST as that gives more information on problems and allows you to re-try emails, etc.

hope that helps,

Graham

[JPReyes]

This is a very common message.

Check that you can reach port 25 and that the IP address of your SAP system is populated on the relay agent of the SMTP Server.

Follow instructions on,
