I know this is an older post, but I also had the issue where I needed to serialize the MailAddress class so I created a serializable version. If you're in a position to use a custom MailAddress class instead of the System.Net.Mail.MailAddress class, this may work for you.

/// 

/// Serializable implementation of .
/// 
[Serializable]
public class MailAddress : System.Net.Mail.MailAddress, ISerializable
{
    // Keep reference to the display name encoding so we can serialize/deserialize the value
    private readonly Encoding _displayNameEncoding;

    public MailAddress(string address)
        : this(address, null, null)
    {
    }

    public MailAddress(string address, string displayName)
        : this(address, displayName, null)
    {
    }

    public MailAddress(string address, string displayName, Encoding displayNameEncoding)
        : base(address, displayName, displayNameEncoding)
    {
        // Keep reference to the supplied displayNameEncoding so we can serialize/deserialize this value
        _displayNameEncoding = displayNameEncoding ?? Encoding.GetEncoding("utf-8");
    }

    public void GetObjectData(SerializationInfo info, StreamingContext context)
    {
        info.AddValue("Address", base.Address);
        info.AddValue("DisplayName", base.DisplayName);
        info.AddValue("DisplayNameEncoding", _displayNameEncoding);
    }

    protected MailAddress(SerializationInfo info, StreamingContext context)
        : this(info.GetString("Address"), info.GetString("DisplayName"), (Encoding)info.GetValue("DisplayNameEncoding", typeof (Encoding)))
    {
    }
}
