I have been using Thunderbird ever since I set up my first email and I like it and am used to it. At some point in time an update was issued and from that point forward I have not been able to send emails or reply to any emails. For what it's worth, I can go through the Comcast website to access my account, but that's a real pain in the butt with a lot of extra steps. It's just so easy to make one mouse click and access it on my desktop. I have contacted Comcast, but they really don't want to deal with me since I no longer have cable service with them (I moved 7 years ago to an area they don't serve). I have a Gmail account and a Charter account and have no trouble with either of those sending or receiving. I really like Thunderbird and would like to figure this issue out and correct it. Please help. Thank you, David Wright When you contact me, as bad as I hate to ask, If I need to respond to an email, please use my Gmail address <redacted>@gmail.com Thanks again.
