That's a pretty nice idea, I think I'll do something similar if/when I
|
|
implement support for searching multiple mailboxes :) The way I'd do it
|
|
is:
|
|
|
|
- Have one "Search all folders" mailbox
|
|
- It has zero messages initially
|
|
- SEARCH done inside it
|
|
1) EXPUNGEs all the existing messages if there are any (although
|
|
unless UID SEARCH is done, the EXPUNGEs can't be sent to client yet)
|
|
2) Adds all the matched messages virtually to the mailbox, and
|
|
returns EXISTS with the new message count (includes the old messages
|
|
with non-UID SEARCH)
|
|
3) Send SEARCH result after the EXISTS reply with listing all the new
|
|
messages.
|
|
|
|
Hmm. I guess this could be generalized to be a virtual folder where the
|
|
search rule gets updated by the SEARCH command.
|
|
|
|
There also exists a draft for searching multiple mailboxes:
