Anyway, a discussion started in #zacon based on a post I thought was interesting about SSL-enabled mail servers and how very very seldomly its actually used for mail: The gist of the story is that mail goes from your client via MTA to another MTA to be delivered and while you might have an SSL enabled session for your gmail interface its highly unlikely that the actual mail will be going over SSL the entire trip. In fact gmail’s SSL certs are for not!

But back to the Alternate DNS names. So one chap in chat ‘dru’ mentioned that he has a single cert for multiple domains, I wasn’t entirely sure this was possible as I have never seen it, however after looking a bit more closely at his SSL certificates on it appeared that all his other linked domains (technically DNS names) were actually in the certificate. This is a great way to find out other domains/dns names linked to your target domain.

Few minutes in PHP and I whipped up a little (but ugly) script to pull this out, check it out at
