In case someone wants to try: http://hg.dovecot.org/dovecot-2.2/rev/0a08efeb3f40
The commit message lists the TODO. So for example if you want to enable it just
for webmail (because quota limits aren’t there yet):
mail_attribute_dict = file:%h/dovecot-attributes
local 10.0.0.0/24 {
imap_metadata = yes
}
Compared to the old metadata plugin, there are some improvements:
- Uses lib-storage attributes internally, which means:
- dsync replicates METADATA
- it will be easy to add support for untagged METADATA notifications to
clients when they change
- SETMETADATA atomically either updates all or none of the changes
Things that work in the METADATA code, but still require lib-dict changes to
work properly:
- Values with unlimited sizes
- Values with binary data (NULs)
