Re: POP3 get the error code 550 relaying denied

Hi galaxyus,

Apologies for the delay in getting a response, hopefully this is no longer an issue?

550 Relaying Denied is a sending error (SMTP) rather than receive error (POP3), and it happens when a given host / domain is not listed under Email / Email Configuration / Receiving Email / Anti-Relay Settings. You need to ensure your SMTP protocol settings have the information for the valid domains and the IP addresses that are allowed to send email through your cluster.
