Hello list,

i use dovecot 2.2.18 compiled on my own and want to report an odd behaviour when using a folder for special_use \Archive. In my case it is not working when using some special foldernames (mbox). I compared to version 2.2.15 which i found pre-packaged on launchpad.net, same behaviour. All other special_use Folder work like expected.

My situation: We authenticate users using mysql-db. also we allow users to store individuell special_use settings in db. this is a way which was recommended by this mailinglist some years ago.

we use a password_query like this: password_query = SELECT inbox as user, password, home as userdb_home, uid AS userdb_uid, gid AS userdb_gid, userdb_import AS userdb_userdb_import FROM mail_users WHERE login = '%u' AND active='Y'

typical column in db looks like this: | username | cryptedpass | path | inboxname | uid | gid | Y | namespace/inbox/mailbox=Sent namespace/inbox/mailbox/Sent/name=Gesendet namespace/inbox/mailbox/Sent/auto=subscribe namespace/inbox/mailbox/Sent/special_use=\Sent namespace/inbox/mailbox=Drafts namespace/inbox/mailbox/Drafts/name=Entwürfe namespace/inbox/mailbox/Drafts/auto=subscribe namespace/inbox/mailbox/Drafts/special_use=\Drafts namespace/inbox/mailbox=Trash namespace/inbox/mailbox/Trash/name=Papierkorb namespace/inbox/mailbox/Trash/auto=subscribe namespace/inbox/mailbox/Trash/special_use=\Trash namespace/inbox/mailbox=Junk namespace/inbox/mailbox/Junk/name=Spam namespace/inbox/mailbox/Junk/auto=subscribe namespace/inbox/mailbox/Junk/special_use=\Junk namespace/inbox/mailbox=Archives namespace/inbox/mailbox/Archives/name=Archiv namespace/inbox/mailbox/Archives/auto=subscribe namespace/inbox/mailbox/Archives/special_use=\Archive |

Now i noticed that in this case the folder Archiv was not binded to special_use \Archive:

• LIST (\NoInferiors \UnMarked \Junk) "/" Spam
• LIST (\NoInferiors \UnMarked \Drafts) "/" Entw&APw-rfe
• LIST (\NoInferiors \UnMarked \Sent) "/" Gesendet
• LIST (\NoInferiors \UnMarked \Trash) "/" Papierkorb
• LIST (\NoInferiors \UnMarked) "/" Archiv
• LIST (\HasNoChildren) "/" INBOX

If i change the name of folder which is binded to special_use \Archive its working again, no other changes:

• LIST (\NoInferiors \UnMarked \Archive) "/" Archiviu or a shorter one:
• LIST (\HasNoChildren \Archive) "/" Arc

It works in most cases, it is not working if i have chosen name "Archiv". It seems also that autocreating of folder is not working if name is "Archiv". I activated the debug settings but was not helpful. Looks the same in all cases:

Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Arc Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive

or: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Archiviu Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive

or the not working one: Debug: Added userdb setting: namespace/inbox/mailbox=Archives Debug: Added userdb setting: namespace/inbox/mailbox/Archives/auto=subscribe Debug: Added userdb setting: namespace/inbox/mailbox/Archives/name=Archiv Debug: Added userdb setting: namespace/inbox/mailbox/Archives/special_use=\Archive

I have no idea what is going wrong here. I have no further hints in my logs. What to do now? Any ideas?

Thanks, Hajo
