my colleague cannot receive all emails from [email protected]. The error the sender gets is shown below:

553 Requested action not taken:
mailbox name not allowed or chunk too large


I did a search online and found a thread that says the Watchguard Firewall Proxied SMTP services is blocking it.

How do I go to this Proxied SMTP server in Watchguard Firewall? Anyone can advise?

thanks and regards,

Access the firewall appliance's web interface. From there you should be able to configure it. It is possible the e-mails are being blocked due to a specific setting or an entry in the SBL.
