550 relay not permitted error


Tiger Privacy 

The error "550 relay not permitted" or "554 relay access denied" means a mail server won't accept outgoing (SMTP) mail from the sender. This is part of how mail servers protect themselves from spam and forged messages. There are several reasons that the error can happen.

Usually it means you need to use a mail server that you have permission to use and configure your mail client for it correctly. Otherwise, you might try using a different outgoing mail server if you can to see if that server can successfully communicate with the downstream server.
