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
dovecot-uidlist:

[root at airframe]:~# du -h ~user/Maildir/.Trash/dovecot-uidlist
8,0K	/home/user/Maildir/.Trash/dovecot-uidlist
[root at airframe]:~# wc -l < ~user/Maildir/.Trash/dovecot-uidlist
104
[root at airframe]:~# ls -1 ~user/Maildir/.Trash/cur/ | wc -l
103
[root at airframe]:~# 
[root at airframe]:~# du -h ~user/Maildir/.Logs.System\ Checks/dovecot-uidlist
664K	/home/user/Maildir/.Logs.System Checks/dovecot-uidlist
[root at airframe]:~# wc -l < ~user/Maildir/.Logs.System\ Checks/dovecot-uidlist
16112
[root at airframe]:~# ls -1 ~user/Maildir/.Logs.System\ Checks/cur/ | wc -l
16110
[root at airframe]:~# 

Thanks a lot Timo, you rock! :-)


Bye,
Thomas


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.
