Connection to SMTP server smtp.comcast.net tmed out.
I use Thunderbird and get the message SMTP server smtp.comcast.net timed out. The last time I successfully sent a message was 5/22/14 - unable to since then. I've changed nothing. SMTP port setting is 465. I was on the phone to Comcast for 2 hours - no success. Also tried ports 524 and 587. Nothing. I can send using Comcast's email (I prefer Thunderbird). Can you help? Thanks.
