SOST error 802 - emails not being sent as recipient unknown

[Former Member]

Hello Experts,

Similar issue has been posted earlier but suggested solutions are not solving my problem.

When user sends mail (having .xls attachment) to XXX@YYY .com (an external email id), the email is being sent.

When the user tries sending a similar mail again, the mail ends with error 802 (recipient unknown error) for SAME recipient.

The mails are being sent sometimes but sometimes they end with above error.

When I try re-sending failed email, it sends out successfully.

Can you please throw some light on this as to why emails are failing only sometimes?

Thanks.

Hi All,

The issue got resolved. we had a new application server added in sysem.

Whenever the mails were being sent from CI/old app servers they went successfully but whenever they were sent via new app server they were failing. Hence, from top view we could see that sometimes emails were transmitting successfully to same email ids while sometimes they were failing.

Solution --- At exchange server, we got new application server IP address added to the relay settings and then it started working fine.

Thanks.

What does the trace show? (/nSCOTT, Utilities --> Overview of send orders. Select message and click Trace)

Trace usually shows exactly what is going on. Sometimes it could be as simple as that a anti-spam software on the mail relay rejecting the message makes it fail intermittently.

Hi Imtiaz,

Note 1496168 talks about relay error but my error is not related to relay rejection.

Note 931596 is for error XS806 but I receive error XS802.

The error in my case says -

The message from the node could not be delivered to recipient <email id> as the recipient is unknown

But the regular solutions are not working in this case because sometimes emails are transmitted successfully while sometimes they fail. Also, if i manually reprocess the failed msgs, they process without errors.

Thanks.

Hi,

Check whether mail send job is running regularly or not.

Hi Sunny,

Yes, I have checked and the job is running regularly (frequency - 3 mins). The the job log doesnu2019t show any warnings/errors as well.

In addition, the SO16/SCOT settings are fine because the emails donu2019t fail daily, they fail sometimes and process successfully when you resend them.

Thanks.

Hello,

Did you find the solution for your problem?

I am facing a similar problem which shows me exactly the same error message.

But to internal e-mail address the program works fine, it doesn't work only for external e-mail adress. I.e.: @gmail, @hotmail and etc.

Thanks,

Hello Ricardo,

Can you please check this settings in SCOT :

SCOT > Your Node(SMTP or..) > Internet SET > Address Area.

For testing u may put * here and see if it works. Late put *@gmail if working.

thnx

Hi Ricardo,

My issue was different, my mails were sometimes being delivered to external and sometimes not.

If you are have issue with sending mails to ANY (gmail/hotmail etc) external email address try following -

Goto tcode SO16 (Shared Office Settings)

In "Send" Tab, all the "send restrictions" should be UNchecked.

In "Addressing" Tab -

UNcheck/UNmark 'Addresses from LDAP Service'

Check/Mark 'Organizational Units'

Check/Mark 'SAP Business Objects'

This should work.

Please confirm back if this solves your problem.

Thanks.
