So, after messing around with these settings for about an hour, I got Thunderbird to finally send mail. I have had this problem before and I have decided to blog about this so everyone can take a shortcut. The correct settings for the q.com SMTP mail server as of 01/19/2010 are:
Thunderbird q.com e-mail settings SMTP
Server name: smtp.live.com
Username: email address
Authentication method: Normal Password
Connection Security: STARTTLS
YOU ARE WELCOME!!! 🙂
Please comment with any questions, or, if q.com decides to change to other settings – comment about it!
