webmail: fix for ignoring error about sending to invalid address

before, an error about an invalid address was not used, causing a delivery
attempt to an empty address (empty localpart/domain). delivery to that address
would fail, but we should've prevented that message from being queued at all.

additionally, an error in adding the message to the queue was ignored too.
