My base concern may be illustrated with the help of that simple telnet
session:

During the whole telnet session, both files "new1" and "new2" remained
empty (i.e. no pseudo-message written to them), no uidvalidity-related
helper file seems to have been created and no uidvalidity-related
function seems to have been called.
And clearly, both mailboxes "new1" and "new2" have received the same
UIDVALIDITY.
Those UIDVALIDITYs appear to be persistent; messages may be added to
and deleted from those mailboxes, those mailboxes may be renamed...
their UIDVALIDITY remain unchanged and equal to 1.
In fact, any additional mailbox is created with that unique and
persistent UIDVALIDITY of 1.
Is this supposed to behave that way?
(note that I quickly tried with dovecot 1.1.16 and could observe the
same behavior)
TIA, Axel
