mail with images does not arrive

When i send an email including images it won ́t arrive at the receiving end, the entire email does not arrive. i don ́t receive an notification of that.
Do i have to change settings or is it just not possible

Does the email go out of the outbox into sent items?  If yes, it is not an eM Client issue as it has passed it off to the server.  If it remains in the outbox, that is a different issue.
