Re: Quotas vs. Trash revisited
I know this is an old problem, but I'd like your thoughts.
We need to apply quotas to our students for the obvious reasons, but
face the old issue of having them hit their quotas and then being unable
to move forward because deleting mail from the client (SquirrelMail)
typically means moving the message to trash, requiring two copies of the
message. This was a known issue when we moved to the system, and we
accepted it on the basis that our front line support could deal with
it. It occurred to me, though, that if we made the user.xxx.Trash
folder a separate quota root with the same quota as their inbox these
problems would go away. Can anyone see any problems with this ?
Attached patch for squirrelmail fixed it for us. It simply tries to copy
mails to trash on delete, if it fails, the mail is deleted anyway.

Note that the name Trash is not significant on the server side and is chosen by the client. At least one client uses small t trash. In an ideal world... wait, in an ideal world they wouldn't use a trash folder, so forget that. Things to look out for: - People who archive mail in Trash.

Sorry, I missed out a piece of the puzzle, which was to automatically expire trash with ipurge after 7 days (and announce the fact of course). - People who archive mail in Trash.

The adivertised interface is SquirrelMail, Trash is one of the auto-created folders. If people want to get themselves into doggy do-do, they have many and more interesting ways to do so.
