Bug renaming folder hierarchies

Tue Feb 23 13:21:38 EET 2021

Hi,

we discovered a major problem with renaming folders with subfolders

testszenario:

folders:

test1
test1/test1-1
test1/test1-2

all 3 folders contain a test message

after renaming the top level folder  test1 to test2 following folders exist:

test2
test2/test1-1
test2/test1-2

the subfolders test1-1 and test1-2 are empty, the top level folder contains the
correct message.

Now renmaing test2 back to test1:

Alle folders again  contain their messages.

So this looks like during renaming the top level folder just the message
references for the subfolders got lost, and with renaming back they are there again.

I can reproduce this behavior both with thunderbird and Horde Webmail as a
client, also it happens with a second different dovecot setup

Here is the dovecot config:
