JAMES-4050 % * in mailbox names #5247

Closed chibenwa closed 2 days ago

chibenwa commented 3 weeks ago

https://issues.apache.org/jira/projects/JAMES/issues/JAMES-4050

* and % in mailbox names get a special meaning in IMAP as they are used as wildcards in IMAP LIST commands.

RFC-3501 do mention side effects of this (extra results might be present in LIST replies for those mailboxes as wildcard WILL be extended) but apparently do not prohibit them.

WHile migrating users from OpenExchange, I did encouter several failures for mailboxe names with those very characters.

I deduce from this that ASF James interpretation of % and * being forbidden in mailbox names is likely too strict and might benefit from being relaxed.

I propose to remove the check by default but propose a JVM option to re-enable it if need be. We would need to add IMAP LIST tests for this.
