outgoing email sloooow
Friends--
For about the last 6 months or so, my outgoing email on comcast has been slow.
Symptom: When I send an email, it tells me it is connecting to comcast, then connected, and then it takes 30 seconds to actually send. This time lapse is about 2/3 of the time. Sometimes, as it did before this problem, it sends immediately. Sometimes it takes longer.
My system: Production environment. Thunderbird 68.10.00 (64-bit) on Ubuntu 18.04. Settings: smtp.comcast.net port 587, starttls. I know other people with different email clients and operating systems are having the same issue.
A few years ago, I had a similar situation, posted here about it, a comcast employee replied, and then the issue stopped about two days later.
Please perform your magic again!

Hang in there folks. We're working on this under the hood a bit. There has been a little progress.

Hi all. I too have been plagued by SLOW outgoing email with Thunderbird. However, I DID find a solution to this issue, from a very unlikely source, a Ubuntu user forum.
https://askubuntu.com/questions/1167509/upgraded-to-18-04-now-thunderbird-will-not-connect-to-server
Here's the solution, and it WORKS!
Comcast servers will not except IPv6.... Disable it in Thunderbird: Here's how:
* In Thunderbird, goto Edit>Preferences>General Tab.
* On the General screen, select "Advanced" tab > "General" subtab, and in the lower right corner find the button "Config Editor".
* Click on it, acknowledge the warning, and scroll a long ways down (or just search) to: network.dns.disableIPv6 (default: false)
* Double-click on the line, and the value will change to "true"
* Back out and Okay
* Shut down and restart Thunderbird
* The email client will connect to the imap server in a flash.
Now, my outgoing Comcast email on Thunderbird (78.8.1) send emails within seconds.
Hope this works for you.
