Typically I've found this to be a problem with the e-mail address (usually when typed in, but could be from a contact entry) that is being used. Maybe it accidentally has a space in it, or some other non-obvious but non-allowed character. Have your user manually (and correctly!) type the address on the To: line and send the message. If it works then a bad address is most likely the cause. Track down how she entered the address the first time and correct it.
