Setting up my home security DVR to send emails when motion detected. I'm using SMTP server (mail.shaw.ca). I know nothing about PORTS and DNS servers but have read a little regarding PORTS and that some ISP's block certain PORTS for outgoing messages. So SHAW SUPPORT my question is 'what port should I be using for my home security DVR using SMTP setup'.
Added info (if it makes a difference): Security DVR is connected to Hitron wifi/modem with a cable.
