Symptoms

Users asked if Siebel does any validation on the "To" address of an outbound email.

On a test with a correct domain name, i.e. @email_address.com, but wrong mailbox or localpart name: "lxxxx". The from address on these emails was a test email address: test_account@email_address.com.

The activity record status for this outbound email in Siebel was changed to "Done" after sending. But there were the following errors in the Comm Outbound Manager tasks screen:


"SMTP DATA error: 503 5.0.0 Need RCPT (recipient).
(commdlv.cpp (578)) SBL-CMO-00152: Send to lxxxx@email_address.com, subject testing with email_address.com email address had error ."


How did Siebel generate this error message? Did Siebel get some message from the SMTP server? I did not get any bounce back for this error email.

The same email was sent out from regular MS Outlook client , and got the following bounce back message:

"From: System Administrator
Sent: Monday, September 19, 2005 2:26 PM
To: lxxxx@email_address.com
Subject: Undeliverable:Testing from outlook

Your message did not reach some or all of the intended recipients.

      Subject:    Testing from outlook

 The following recipient(s) could not be reached:

            The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.
