Hi Arnold,
thanks for your assistance. I solved the issue right now by changing
prefix = Shared/%%u/ to prefix = Shared/%%n/
This omits the @mydomain.de part which holds the dot causing the trouble. Why this became a problem due to the update I wouldn't know.
Regards
Lothar

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.
