It's not a problem.

I deleted some messages from my sentbox but they still won't send.
The Sentbox naturally remains full. This is normal. It does not affect PMs going out.

Does this mean that the addressees' PM inboxes are full?
You would get a notice if your recipient cannot receive any more PMs due to his Inbox being full. PMs in your Outbox just means the recipient hasn't opened them yet.
