[Dovecot] INBOX can't be deleted

[Marten Lehmann]

Hi,

surely it can't and it shouldn't. I'm just wondering why a check for 
"INBOX" is done in src/imap/cmd-delete.c AND 
src/lib-storage/index/maildir/maildir-storage.c. The first is clear 
because it gives an imap-error to the client. But for which case is the 
check in maildir-sorage.c? Just to be absolutely sure?
The reason for me to ask is, because I need to disable deletions for 
five folders: Drafts, Infected, Junk, Sent and Trash. A certain 
webmail-interface and spamfilter will rely on these folders, so nobody 
shall be able to delete or rename them. First I placed the checks in 
cmd-delete.c. Should I place them in maildir-storage.c additionally? In 
normal circumstance, the check in maildir-storage.c should never be 
reached, right?

Marten
