Wow ... yes, this did in fact help a lot! :-) Deleting a message in Thunderbird
(= moving it to the Trash folder) is now an instant action again, rather than
the 2-3+ seconds (and sometimes even more) it used to take before with the huge

PS: I would have told you earlier, but I didn't even know that dovecot was
    supposed to shrink its dovecot-uidlist files every now and then. ;-) I
    only checked these files when the discussion came up recently, and only
    then I found out that I actually suffered from the same problem.
