Hi Lothar,
I haven't yet had the opportunity to go deep into Dovecot engineering /
development, (so please correct me if necessary anyone).
I have experienced this exception where attempting to copy mailbox data
within a client from IMAP account to IMAP account, but I have not had
it cause a mailbox to become inaccessible.
The reason was because Maildir++ format uses the "." separator to
delineate child directories, and therefore the character is illegal in
mailbox names. The issue was addressed by either changing the
filesystem layout to LAYOUT=fs or by changing the mailbox format
altogether to e.g. sdbox.
> location = maildir:%%h:INDEX=%h/shared/%%u
I can see from your configuration that the LAYOUT is not set as fs, so
I would assume is still using Maildir++.
Perhaps this setting was lost during the upgrade?

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.
Lothar Schilling
