CUNY Academic Commons

No, we don't keep a master list. We validate email addresses at the time of registration, but we use a wildcard, which means we don't keep track of the specific email addresses.

I just took a minute to parse out all email domains actually in use on the Commons. I sorted them by frequency and manually removed those that are obviously unconnected to CUNY. You can see from the list that many are clearly typos. You can also see that individual campuses have a good deal of latitude on subdomains etc, so that it's likely impossible to compile a truly comprehensive whitelist.
