Twitter has fucked up their email setup
Reverse DNS no longer matches (x.com vs twitter.com) and therefore my mail server rightfully rejects emails from Twitter.A user of my mail server made me notice, as I myself no longer use Twitter.
Well, that's what comes of this domain change thing. Though I have done a domain migration for an organization before and therefore, this kind of thing is funny.
