"550 relay not permitted"

I think your might facing error when u try to send email from a network other than that on which the smtp server resides. This is because most ISPs block this to prevent spam.

To solve this problem, please change setting of your Outlook account by clicking on More Settings > Outgoing Server and check the My outgoing server (SMTP) requires authentication.

To check whether your email provider supports authentication:

1. Start > Run > cmd
2. telnet smtp.yourservername.here 110
If successful, it should tell you you're connected.
3. ehlo smtp.yourservername.here
4. It will return a list. If you see something in the list that says AUTHENTICATION it supports it.
