Please add support for the IMAP QUOTA extension (RFC 2087)
Dear Sylpheed developer(s),
please add support for the IMAP QUOTA extension (RFC 2087), so that it becomes possible to check the quota of IMAP accounts/mailboxes in Sylpheed.
Thunderbird already does have this feature (it's possible to check the quota inside Thunderbird) and there even is an extension available which makes the quota display in Thunderbird's status bar, see: https://addons.mozilla.org/de/thunderbird/addon/display-quota/.
By the way, I do not speak Japanese, but it looks like this already had been requested some time earlier on the japanese Sylpheed mailing list, see:
It would be much appreciated.
