I've been using Thunderbird with my hotmail account for a few months now but, after the first month it stopped sending emails. It's not because of a difference between TB2 and TB3 and it's not my configurations (I've tried them all), and it's not that my ports are blocked (http://bro.ws/772173L).

The problem appears to be that although all hotmail servers require STARTLS, many of them (particularly the ones I connect to) don't support STARTLS. I was wondering if anyone could confirm this or offer another solution that I haven't thought of (I've googled for hours to find a cure).

If all else fails I guess I can try again to create a GMail account but, every time I do I'm the one who gets 'randomly' selected to verify with a text message (I don't have texting...)
