Last updated on DECEMBER 19, 2022

Applies to:

Oracle Email Center - Version 12.2.5 and later
Information in this document applies to any platform.


When attempting to reply to email, the following error occurs.

" javax.mail.SendFailedException: Invalid Addresses; nested exception is: com.sun.mail.smtp.SMTPAddres. SMTPAddressFailedException: 550.5.1 ..User unkown"

The issue can be reproduced at will with the following steps:

1. Set the Profile option "IEM: Admin: Reply To All" to ‘Yes’ at site level.

2. Sender ( sends email to <> (This email account is not an active email account in Email Center)
  According to a rule in MS-Outlook, all emails, which will be sent to <> will be forwarded to (which is an active email account within Email Center).

3. Navigate to (R) Email Center Agent Console -> Email Center Agent Console -> Messages -> My Inbox

4. Open the email

5. Within the reply, “To” is filled with "<>; <NAME>."
  So the recipients address <> has been cut. Recipient is not a valid email address:

6. When now clicking on reply without having repaired the erroneous To-string, error page will be raised.
