[imp] delete emails directly and permanently

[Khanh Truong]

Hi all,

My IMAP server enforces quotas for users. The problem is, when users reach
their quota, they cannot delete messages to reduce their usage. Everytime
this happens, I have to be involved and increase the quota then reduce it
again when they've cleaned up their mailbox.
Is there an option to delete messages permanently when you click on Delete?
Right now, when you click Delete, it just moves the messages to Trash or it
marks the messages as Deleted. When quota is reached, moving deleted
messages to Trash doesn't work because it complains there's not enough space
and marking messages as Deleted doesn't work either because they're still
there. Is there a way around this so that users can resolve the problem
themselves and not have to involve the administrator?

Thanks,
Ken
