Last night around 8:30 EST, my emails stopped working on Thunderbird (both sending and receiving). I can still both send and receive emails via Webmail (Comcast) and on my BlackBerry, so the problem would appear to be Thunderbird-related.

When I click "Get Messages," I see: "Thunderbird--Failed to connected to server mail.comcast.net."

When I attempt to send a message, I see: "An error occurred while sending mail: The mail server sent an incorrect greeting: concurrent connection limit in Avast exceeded (pass:0, processes:thunderbird.exe[50])."

(I have made no recent changes in Avast.)

Today I upgraded to Thunderbird 52.8. That made no difference one way or another; I couldn't send or receive emails either before or after the upgrade.

Any advice? I can use comcast.net, but I'd much rather use Thunderbird! Thank you.

Thanks so much for the link, which does indeed look potentially helpful--though I don't know for sure, since I didn't end up needing it. I left home on a trip, and when I returned and booted up my desktop computer, my Thunderbird inbox suddenly started loading. I was able both to send and receive emails. I had made no changes, and I have no idea either what had caused the original problem or what had made it go away.
