Assuming button4 is what sends the email, if you do not want attachments you need to check if your attachment field is blank. For example:

private void button4_Click(object sender, EventArgs e){
    if(Anexostxt.Text != "") {
        msg.Attachments.Add(new Attachment(Anexostxt.Text));
    }
    if(anexos2.Text != "") {
        msg.Attachments.Add(new Attachment(anexos2.Text));
    }
}

This is just a basic principle, you will probably need additional validations (for example, check if the fields do not only contain spaces, or point to a valid file, etc.)
