Background: 1. Comcast provides a forwarding address (missedspam@comcastdotnet) to which it's customers may forward junk to help prevent repeats. 2. To use Comcast's spam recognition service, I created a filter for the junk folder: "forward to missedspam@comcast."

Problem: When I run that filter for the junk folder, obviously it tries to send a bunch of emails at once and Thunderbird give an error message: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h1p-028434.sys.comcast.net resomta-h1p-028434.sys.comcast.net Too many sessions opened."

How can I prevent this?

Hello

I don't quite see a better way than to create a local folder for that, enable the filter on this folder, move a bunch of mails to it, then run the filter, delete the mail in the local folder, repeat. Thunderbird is not a mail server and can't really implement sending rate limitation for this very particular use case.

I find your basic idea a bit disturbing by the way: if even the junk classification of Thunderbird mischaracterizes a mail, it could blacklist someone from sending you mail without you having any idea of it. Spam detection is not an exact science, so I'd avoid having this filter run automatically.
