Okay, I figured it out in a test environment.

The offset is a red herring and shouldn't be included, so the
following does what I need:

mailbox_default_options: 3

 Default “options” field for the mailbox on create. You’ll
 want to know what you’re doing before setting this, but it
 can apply some default annotations like duplicate supression

Okay, I do need it.  I have a legacy server with Cyrus IMAPD 2.3.x
installed, and I need to enable the CONDSTORE flag by default on all
newly created mailboxes/subfolders.

- From imap/mailbox.h:

#define OPT_POP3_NEW_UIDL (1<<0)
#define OPT_IMAP_CONDSTORE (1<<1)
#define OPT_IMAP_SHAREDSEEN (1<<2)
#define OPT_IMAP_DUPDELIVER (1<<3)

And also:

#define OFFSET_MAILBOX_OPTIONS 60

So given that POP3_NEW_UIDL appears to be on by default and the others
are all off, would the syntax be:

(Offset int 60 + (1 << 1 = int 2) + (1 << 0 = int 1) = int 63)

mailbox_default_options: 63

Am I on the right track?

Re: Syntax for mailbox_default_options

[ellie timoney]

I believe it's an integer bitmask of the OPT_* values that are defined in 
imap/mailbox.h in the source.

The sparse documentation suggests it's for developer, rather than normal 
administrator use, maybe for rigging up tests?  It's included in the imapd.conf 
man page because that man page is autogenerated from the code that processes 
the options.

Unless you've got something in particular you're trying to do, I'd probably 
just leave it alone. :)

Cheers,

ellie
