I just upgraded dovecot from 2.1.7 to 2.2.13, and my previously working configuration broke.
I have one user with an empty prefix
in his default namespace:
Error: XXXX: Initialization failed: namespace configuration error: list=yes requires prefix=yes to end with separator
Error: Invalid user settings. Refer to server log for more information.
The prefix is set to empty via the userdb:
XXXX:YYYY::::::userdb_namespace/inbox/prefix=
Unfortunately, I could not find any other configuration. With
XXXX:YYYY::::::userdb_namespace/inbox/prefix=.
I get
namespace configuration error: list=yes requires prefix=. not to start with separator
What is the correct way to get the old behaviour with 2.2.13?
