Mail.dll IMAP client supports expression syntax to build simple and complex email search queries:

List<long> uids = imap.Search().Where(
    Expression.From("delas@mail.com"));

using Expression.And (unseen email from specific email):

List<long> uids = imap.Search().Where(
    Expression.And(
        Expression.From("delas@mail.com"),
        Expression.HasFlag(Flag.Unseen)));

Last element in uids list is the newest email.
