I posted last week about Hotmail breaking email headers – it’s starting to be noticed a little more, and unfortunately there isn’t a solution yet. I’ve looked at rewriting the headers on my own (exim-based) mailservers but frankly it’s a pain in the arse and I don’t really want to frig something when it’s Hotmail that should be fixing it.

More links (including info on Roundcube and Thunderbird):

It’s bloody annoying, and tedious Microsoft won’t actually fix it. Do they not have a QA dept?
