Oh please ...

This entire thing is silly! There already is an easy method you can use 
to do this in thunderbird!

Create a new folder for Ubuntu Mailing List in thunderbird, name it 
whatever you want, doesn't matter.

Go to "Tools>Message Filters" and select "new."

Call it ubuntu users or whatever, something that you can remember what 
it's for by looking at the name.  In the first box, select "body" as the 
criteria to match on the left, "contains" as the criteria to match in 
the middle, and in the white space after it, paste 
ubuntu-users at lists.ubuntu.com

Then, in the box below, make the action on the left be "Move Message To" 
and have it move to the folder you created.

There! Now all mail on this mailing list will go in that folder! See? 
It's not that hard! There already is a regular piece of data included in 
every ubuntu-mailing-list piece of mail, and that's the footer appended 
by the ubuntu-users mailing list, which includes 
ubuntu-users at lists.ubuntu.com !

Hooray! Problem solved!
