I don't run any servers on Shaw anymore, I use them strictly for connectivity. I know that a couple of years ago they intercepted outgoing connections on port 25 for residential connections, I do not know the state of SOHO. They did this then without notice, so it would not surprise me if that behavior persists. I would expect that most SOHO customers do not run their own servers, so they have just implemented a change in response to a SPAM or virus threat. They have also traditionally tended to do a rolling deployment so they can judge end user impact. You may just be unlucky enough to be one of the first.
The solution is to use a smarthost relay. I am finding that more and more I am pushing more mail accounts on to hosted solutions, such as Google Apps, Fastmail and so on. I personally only have one domain left that I directly host, and since it is in a local co-lo facility the cost/benefit ratio does not make sense. I am still sorting out alternatives (it is looking like a VPS is the only really viable option, and that is not much different than trusting Google not to snoop or mess with your data). When using a smart host to relay, you still have to use a different port, typically 587 or 465, and typically you would use encryption and authentication which can get a little tricky.
