Private Messages Disabled

It's the second time I receive a private message but when I try to answer I see this error:



Now, having PM disabled is fine but users being able to SEND PMes but not to RECEIVE answers because their PM are disabled doesn't make much sense to me.

May this be fixed someway? E.G. Alert telling users "be aware, your incoming PM is disabled" or preventing user from sending PMes at all if messages are disabled (why should somebody be able to send messages but not to receive them?)

This is just my feedback.
