550 mf-508: Sender Policy - Relay Denied

[21russell]

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?
