Automatically Rename Mailboxes

[ms419 at freezone.co.uk]

I would like to periodically automatically rename mailboxes. The size 
of some mailboxes can quickly grow out of hand. Say, once a month, I'd 
like "INBOX.busy-list" moved to "INBOX.busy-list.20040418" - for 
instance.

I thought first of a cron job, calling "cyradm", but this is the limit 
of my voodoo. From it's man page, I can't figure out how to call 
"cyradm" in such a way that it will rename all mailboxes 
"INBOX.<mailbox>" to "INBOX.<mailbox>.<date>".

Another problem I foresee is authentication: It can't be done 
automatically if I must enter a password. One solution may be to use an 
SSL key and SASL EXTERNAL authentication ... I haven't tried yet.

I would be very grateful for some input!

Thanks!

Jack
