OX 6.10 - Problem with automatic mbox detection and Cyrus delayed expunge

[janny_buh]

I'm using OX SE 6.10 with Cyrus 2.3 and I noticed that a "test" folder is created (and immediately deleted) in the user inbox for each user login in order to test for the "mbox" feature.

For example:
...
CREATE INBOX/1251905076703
LIST "" INBOX/1251905076703
LIST (\HasNoChildren) "/" "INBOX/1251905076703"
DELETE INBOX/1251905076703
...

The problem is that with Cyrus this behaviour leads to a number of junk folders kept for some period due to the "delayed expunge" feature of Cyrus...

After some code inspection I found that the IMAPDefaultFolderChecker.checkDefaultFolders(Strin g) (in particular, the new IMAPCommandsCollection.supportsFolderType method) is responsible for the creation/deletion of those temporary folders.

With previous OX version, using the com.openexchange.imap.mboxEnable I can manually turn on/off the mbox support, but with OX 6.10 the mbox "must be" always automatically detected.

Could mbox auto-detection mechanism be improved in the next OX version?
For example allowing the administrator to turn on/off mbox by property (as previous OX versions), or deducing mbox support from imap server type or something else.
Thanks for your work!

Well, with upcoming release this check is only done once per IMAP server.

Hope this is OK for you.

Your solution seems very appropriate.
Is this feature already planned for the upcoming OX 6.12 release?
