[SM-USERS] Quota error when deleting multiple messages

[tonix (Antonio Nati)]

SM 1.4.5 (courier-imap 4.0.4).

When deleting (i.e. moving to trash) multiple messages, I've got this error.

ERRORE: non è stato possibile completare la richiesta.
Domanda: COPY 16,21 "INBOX.Trash"
Motivo dato: [ALERT] You exceeded your mail quota.

But, deleting each single message alone does not give any error.

The same problems is for every copy/move/delete operation.

So, it looks like SM asks courier-imap to move all messages grouped together when moving them to trash, so they need en enourmous amount of free space for the group operation.

I feel they should move messages one by one, so the need for free space will be minimal.

Where is the problem? Is a courier problem, or it's a problem SM have with all imap servers?
