For any educational institutions on this list - what has been the impact on your mail services once your ISP started blocking port 25 - what if any was the backlash - and how difficult was it to provide alternatives ...587,465 etc ...
Why would an ISP block port 25 for .edu customers? The universities I'm familiar with have PI space vs PA. Comparatively, that should be the boundary to determine whether to block 25 or not, IMO. -M<
