Wired

This start happening recently, first time I ignored that but now I got another user with same issue… user is forrwarding email to someone else outside of our notes nomain and gets NDR bounced back with following message:

Your document: subject line.

was not delivered to: user@domain.com

because: 550 5.1.1 User unknown

where user@domian.com is sender and he is sending email to 2 receipients, so why is it telling him it was not delivered to himself when he is not on receipient list, and obviously he exist?

any idea?

Subject: wired…

my hunch is that the recipients’ mail server has no knowledge of at least one of the recipients, and has been configured incorrectly on sending a bounce-back message to the sender.
