Hi Thomas, Thank you for your reply.
SMTP2Go provides an SMTP Mail Relay service. I checked their support information yesterday and it appears that I need to have my mail domain fully verified to allow me to send through their Relay service. Hence the log messages talking about “Verified Senders”. I have now verified my domain “sidoti.id.au”. Your simple suggestion to use the “-r” option with the “mail” command is a nice solution. It overcomes the hostname issue as I am not using a real FQDN for the hostname. No issues with sending emails now.
