[tech] Email changes: Migration away from IronPorts for sending

[James Arcus]

Hi all,

Just a quick update on the progress of preparing to migrate away from 
the UWA IronPorts.

Following some further discussion with Daniel from UWA IT, and a check 
of the firewall rules in place, we've decided that it will be better for 
us to send mail outbound directly from UCC, instead of paying for a 
commercial relay service.

I've asked for reverse DNS records to be added for the IPs we're 
planning to use for our mail servers. Once that's complete, we can begin 
testing and migrating away from using `smtp.uwa.edu.au` as our mail 
relay host.

I'll let people know when we are ready to start, because we'll need to 
keep an eye out for any increase in rejections or mail being spam filtered.

Cheers,

James [MPT]
