what is permfail

[DirtManDan]

I'm using Outlook 2002. I can receive emails OK and can send e-mail OK, but
when I send emails in Bcc: I get the the error message "550 [PERMFAIL]
destination not valid within DNS". I used to be able to send Bcc: OK.

Would anyone have information that will help me troubleshoot this issue?

Regards,
Dan

The people who run your mailserver (the one you have set up as your SMTP
server) should be able to.
