For the record, I don't believe this impacts custom domains. I did a few searches on some of my custom domains and they return things like the following response message:
We haven't information about @yourdomain.com
Quite useful, thanks! It looks like custom domains are in fact not affected. That's a relief. However, with the vast amount of accounts GMail must have, 5 million accounts seems like a small number. Lucky I wasn't in there.
Link to the leak source wasn't working for me. Anyone know the source?
is this a trojan collecting targets for bots to crack?
