INBOX.INBOX.

[Wolfgang Breyha]

Hi!

I'm not sure if this is a bug or intended...

cyrus checks for mailbox names including "INBOX.INBOX." since 2.5 and
prevents creation to stop buggy clients like Apple Mail from recursing.

But it still allows eg.
INBOX.INBOX.Trash
since the check is done after conversion to the internal user.<uid>... format.

INBOX.INBOX.(Trash|Sent|Drafts) is widely used by K9 (and others) as it
seems. K9 fixed it "recently" ...
https://github.com/k9mail/k-9/issues/701
... but it seems existing configs still use this pattern.

Does cyrus intentionally allow user.<uid>.INBOX. and only prevents
user.<uid>.INBOX.INBOX.... or is this a bug and will be changed in future
versions?

With kind regards,
Wolfgang Breyha
