Hi,
I have been using TPG SMTP service to relay emails without issues.
However since today all my email bounced back with: "550 mf-508: Sender Policy - Relay Denied"
I am unable to send email. Please help.

Hi @21russell
How's your outgoing mail? Is it going through now?
Are you using an email client like outlook, thunderbird, etc.? Can you try on the webmail?
