onetapu:clinty: Just to confirm:
The brother printer is connected to a network that uses Spark as an ISP.
You are trying to email the faxes to an @xtra.co.nz address
If this is correct I can sort out a stunnel INI file for you tmrw at work

That is correct, Clint. And the email address of the printer is the same as my email address. How does the stunnel work?
STunnel is a piece of software that run's on your computer which will mean you need to keep your PC on for the printer to be able to send emails.

Basically you are looking to do what is documented here, but instead of to Microsoft it would connect to the Yahoo SMTP servers.
It means that the Printer connects to your PC, then the PC creates the SSL connection to Yahoo to allow it to send the email. Rather than the printer talking directly to the now retired Xtra SMTP servers.
You will need to be able to put a username and password into the brother printer to login to the SMTP server.

That should sort you out, as long as you can put in your xtra username and password into the Brother MFC.
