Character not allowed in mailbox name

22 Jul 2019


      Hi everybody,
after an update this morning to dovecot 2.3.7 we cannot connect to our
shared mailboxes anymore. The error message as issued in Thunderbird:
"Character not allowed in mailbox name '.'"
I didn't change anything about the configuration. Output of dovecot -n:
[...]
namespace {
list = children
location = maildir:%%h:INDEX=%h/shared/%%u
prefix = Shared/%%u/
separator = /
subscriptions = yes
type = shared
}
[...]
Any help would be appreciated, thank you very much.
