Yesterday evening I noticed an issue with certain emails not arriving from the server which hosts Kametsu where any emails to the Hotmail/Live/MSN email addresses were being rejected by Microsoft.
This is due to the server being incorrectly detected as sending out spam emails.
I have applied to Microsoft to have this restriction removed, and they have agreed to do so, though they have restricted the number of emails that come through. Hopefully this should not affect us however.
Therefore, any topic replies, private messages, or email notifications to Hotmail users will not have come through between 2016-01-05 at 15:45 GMT+0 and 2016-01-06 at 00:30 GMT+0.
There may be some issues with emails from Kametsu for a little while, I'll be taking a more in depth look at this in the evening.
If anyone notices anything unusual in the emails, let me know.
