Problem retrieving emails

I’m developing an email client for my company, and I’ve received it as explained in the following link: https://docs.aspose.com/display/emailnet/Working+with+Messages+from+IMAP+ Server

Code sample:

using (var imapClient = new ImapClient(contaEmail.ServidorEntrada, contaEmail.PortaEntrada))
{
	imapClient.Username = contaEmail.Login;
	imapClient.Password = contaEmail.RecuperarSenha();
	var evnt = new ManualResetEvent(false);
	while (true)
	{
		var builder = new ImapQueryBuilder();
		builder.InternalDate.Greater(DataUltimaSincronizacao.ToUniversalTime(), DateComparisonType.ByDateTime);
		var query = builder.GetQuery();
		var pageInfo = imapClient.ListMessagesByPage(ImapFolderInfo.InBox, query, 15);
		var messages = pageInfo.Items.ToList();
		while (!pageInfo.LastPage)
		{
			pageInfo = imapClient.ListMessagesByPage(ImapFolderInfo.InBox, query, pageInfo.NextPage);
			messages.AddRange(pageInfo.Items);
		}
		if (messages.Any())
		{
			foreach (var imapMessageInfo in messages)
			{
				var mailMessage = imapClient.FetchMessage(imapMessageInfo.SequenceNumber);
				OnRecebeuEmail(mailMessage, imapMessageInfo.InternalDate, imapMessageInfo.IsRead);
			}
		}
		evnt.WaitOne(TimeSpan.FromMinutes(1));
		evnt.Reset();
	}
}

The problem: If I receive an email after the loop has started, it is not retrieved in the ListMessagesByPage, only if I close the thread and start another, which subsequently rebuilds the ImapClient.

I simulated this in version 17.11 and 18.2.

  • This error occurs in both Imap and Pop3.
  • I’m still not using StartMonitoring because I have another bug open with regard to this case.
