How to ignore data annotation validation in asp.net MVC

Is there any way to ignore data annotation validation in asp.net validation?

Look at the following case:

I have this metadata class for a message entity

public class MessageMetaData
{
    [Required(ErrorMessage="This field is required")]        
    public int[] To { get; set; }

    [Required(ErrorMessage = "This field is required")]        
    public string Title { get; set; }

    [Required(ErrorMessage = "This field is required")]        
    public string Body { get; set; }
}

and this is my message class:

public partial class message
{
    public message()
    {
        this.FilesRelatedToTheMessage = new HashSet<file>();
        this.Receivers = new HashSet<MessageReceiversConnector>();
    }

    public int id { get; set; }
    public string Title { get; set; }
    public string Body { get; set; }
    public Nullable<int> C_From { get; set; }
    public Nullable<int> AreaId { get; set; }
    public Nullable<int> Project { get; set; }
    public string Status { get; set; }
    public System.DateTime DateOfCreation { get; set; }

    public virtual ICollection<file> FilesRelatedToTheMessage { get; set; }
    public virtual EventsArea EventsArea { get; set; }
    public virtual project ProjectTheMessageRelatedTo { get; set; }
    public virtual ICollection<MessageReceiversConnector> Receivers { get; set; }
    public virtual user Sender { get; set; }
}

[MetadataType(typeof(MessageMetaData))]
public partial class message
{
    public int[] To { get; set; }
    public int[] Areas { get; set; }
    private MessageDTO mdto = new MessageDTO();
    public MessageDTO MDTO { get { return this.mdto; } set { this.mdto = value; } }
}

When I want to store a message as a draft message, one of the properties might not be sent. Is there any way to handle this issue?

Edit:

this is my DraftMessage action 

    public string DraftMessage(message draftMessage, string status)
    {
        if (status == "new")
        {
            draftMessage.Status = "DR";
            draftMessage.DateOfCreation = DateTime.UtcNow;
            draftMessage.C_From = CurrentUser.Id;
            context.messages.Add(draftMessage);
            foreach (int receiverId in draftMessage.To)
            {
                if (context.users.Any(user => user.user_id == receiverId && (user.DepartmentOfTheUser.Company == CurrentUser.Company || user.DepartmentOfTheUser.CompanyOfTheDepartment.CompanyCustomers.Any(cus => cus.customer_of == CurrentUser.Company) || user.DepartmentOfTheUser.CompanyOfTheDepartment.CompanySuppliers.Any(supp => supp.supplier_of == CurrentUser.Company))))
                {
                    context.MessageReceiversConnectors.Add(new MessageReceiversConnector() { MessageId = draftMessage.id, ReceiverId = receiverId, MessageStatus = "DR" });
                }
            }
        }

        context.SaveChanges();

        return "draft";
    }

here it throws message on context.SaveChanges(); because of validation, the fields in the database are all nullable but it throws exception due to metadata class.

Maybe it is worth to make two ViewModels. One for Draft message and another for message you want to send.
