It appears this method below only works for the received Message-ID, but I need to search for the sending server Message-ID in a bounced email. Or perhaps a simple plain text search of the entire contents shown when I open View Source?

I can see it there as pictured below, how do I use search to find all emails with that in the header?

Basically I have a variety of sending servers that are bouncing back to me and I want to know who is responsible for which messages. I can manually find that by viewing source on each email no problem, but want to search all and get all at once.

In the search results overview, incorrect email addresses are sometimes additionally displayed in the 'Recipient' and 'From' columns. (Taken from the email directly located above it.)

I have been using Thunderbird for a while.. I could always filter messages easily to help with mailbox cleanup, now it seems to have stopped working or a setting has automatically changed.. When activating Quick Filter, I could type in the 'Filter Messages' box and it would start listing the mails in that inbox as I typed, now it doesn't happen anymore..
