While sending alerts via obiee 10g we are getting below error in log. Alert displays in dashboard but not receiving emails.
any help will be highly appreciated.
The message "5.7.1 Client was not authenticated" is something your smtp server is telling you.
Did it ever worked before? If yes and nobody changed the config get in touch with your SMTP admin to debug that.
If you google that message you find many results related to Exchange.
If you never used it before or it never worked double check your mail setup in OBIEE and make sure everything is setup correctly.
