My home automation system (an OmniLT by HAI) is able to send emails when certain triggers occur, anything from the intruder alarm sounding to temperature variations etc. However it is a little old fashioned and it can only speak good ole' SMTP over port 25. None of this modern SSL/TLS stuff :-)
Well for sometime now, most ISPs, including Google's GMail will only accept secure connections and thus this is a problem... or is it...
It turns out that Google provides a legacy connection point, I am avoiding the term 'back-door'.
They will relay SMTP on port 25 providing you satisfy the following criteria:
- You have (and use) an account.
- You only send to another GMail user
In other words, it is a service they provide for their customers and the traffic remains within their eco-system.
Here are the details:
Host Name: gmail-smtp-in.l.google.com
Port: 25
Gmail account credentials are required.
Shhhhhhh... Don't tell anyone...
Cheers!
