Has anyone successfully configured one of these cards fro email notifications through Google Apps? I believe there is a piece missing on their config page if I am using aspmx.l.google.com as there is not a STARTTLS option using plain old port 25. This works flawlessly on most devices on our network and our DMARC and SPF records are set to allow emails from our WAN IP.
I have a feeling it isn't supported so I may just have to relay off of another server somehow. I don't want to use an internal server in the that server is down.
