A PHP Error was encountered

Severity: Warning

Usually this error means your mail server requires SMTP authentication to send emails. You may have two options, one is to change to another SMTP server that does not require authentication.

The other option will be to put the credentials in your config. Please check this page, and try with the smtp_user/smtp_pass settings.

If you post your config settings and the use case, I'll be able to provide you with more details.

To be clear, "550 The address is not valid." means that the mail server cannot accept your email because it cannot find the mailbox "[email protected]". Are you sure that you have configured your mailserver properly?
