You can use Imap.GetMessageInfoByUID(List uids) or its Sequence overload.

You'll get basic email info such as From, To, Subject and also obtain email structure e.g. attachment count, names:


using (Imap imap = new Imap())
    imap.Connect("imap.example.com");   // or ConnectSSL
    imap.UseBestLogin("user", "password");


    List<long> uids = imap.Search(Flag.Unseen);
    List<MessageInfo> infos = imap.GetMessageInfoByUID(uids);

    foreach (MessageInfo info in infos)
        string subject = info.Envelope.Subject;
        IList<MailBox> from = info.Envelope.From);
        IList<MailAddress> to = info.Envelope.To);

        foreach (MimeStructure attachment in 
            string fileName = attachment.SafeFileName;
            long size = attachment.Size;

In this method, all information is taken by the function and that is why it is not good for performance. I need flags with Uid only in one list for that I need to take all unwanted data.
Use Imap.GetFlagsByUID then.

GetMessageInfoByUID gets ENVELOPE, BODYSTRUCTURE and FLAGS. You can obtain each of those individually (GetFlagsByUID, GetBodyStructureByUID, GetEnvelopeByUID).
Great, Thank you.
