How do you resolve the error "The mail server sent an incorrect greeting"?
I began receiving this error several days ago. The screen shot is below. I've contacted Comcast and they feel it is an issue with the client program. I am able to use their web email. And it has been intermittent. I can receive at any time, but seem to get the error message when sending during the day. It has been fine early morning and in the evenings. I have verified that my outgoing server settings match those on the support page, and the program has been running fine for months. Any help would be appreciated.

What are you smtp settings? The recommendation is smtp.comcast.net on port 465, SSL/TLS security, authentication = normal password, User name = email address.

What is your antivirus, and is it scanning secure (SSL) connections or the TB profile folder?
Outgoing mail settings attached below. I am using AVG (not the free version) and do not have the "Scan outbound emails" box checked. I did disable the program once and still was not able to send. My outbound settings are the same as the link you sent. I have not altered them.
Try it with HTTPS scanning disabled, or better, run Windows in safe mode with networking to see if any component of AVG is interfering with sending. Hard to say why it would work at certain times of the day, unless you control some other factor such as a VPN.
Tried with HTTPS disabled. Still the same. Tried to boot in safe mode with networking but I could not connect to the internet. At some point last week I had turned up my new subscription with AVG. Sorry I had not mentioned that earlier. I have posted over on the AVG site to see if they have an answer for this.

The other obvious component to disable is the Mail Shield. The general recommendation is to add the TB profile folder as an exception or exclusion in the AV settings, leaving the real-time background scanner in place. Otherwise, if Windows safe mode isn't feasible, a temporary uninstall of AVG might be a useful test.
After my last post I went into AVG and hit the "repair app" button under troubleshooting. Was able to send myself an email a minute or two later. That was mid-afternoon. I'll use your suggestion tomorrow if this has not been resolved. I appreciate your help. Not sure if the time of day is a red herring or not.
