E-mails to Microsoft addresses blocked

It seems that postfix was insufficiently secure, and hisoka’s IP ended up on several blacklists. I’ve taken steps (setting up SPF and DKIM mostly) and we’re now essentially in the clear, except for one thing.

E-mails sent from tigris.fr to Microsoft addresses (including, but probably not limited to, hotmail and outlook addresses) are blocked. I’m trying to get this resolved, but in the mean time, there is no real solution but to use another email transport.

Sorry for the inconvenience. Let’s hope this gets resolved eventually.
