When you send a message it can be recalled and deleted if the recipient has not read it yet.
If the recipient HAS already read the message, it can't be deleted by the sender, but will auto-deleted after x days based on the setting in the UDDEIM config (in the admin backend).
well, i am aware of what you said, syrinx. but why only auto deletion?
why there is no provision to delete outbox items as we please.
we may need to keep some and remove others, right?
i hope the next version will handle it.
