Sono stato alla ricerca di una risposta a questa domanda, ma senza fare affidamento su un server Exchange, e di utilizzare invece un server IMAP. Non so se questo rientra nello scopo della domanda, ma ho trovato la ricerca di "Ottenere un messaggio di posta inviato nella cartella di posta", che era il mio problema in primo luogo.
non hanno trovato una risposta diretta da nessuna parte ho costruito la mia propria soluzione basata su:
sto attuazione del metodo di salvataggio come estensione di SmtpClient così, invece di di .Send()
useremo .SendAndSaveMessageToIMAP()
.

private static void SendCommandAndReceiveResponse(string command)
{
try
{
if (command != "")
{
if (tcpc.Connected)
{
dummy = System.Text.Encoding.ASCII.GetBytes(command);
ssl.Write(dummy, 0, dummy.Length);
}
else
{
throw new System.ApplicationException("TCP CONNECTION DISCONNECTED");
}
}
ssl.Flush();
buffer = new byte[2048];
bytes = ssl.Read(buffer, 0, 2048);
sb.Append(System.Text.Encoding.ASCII.GetString(buffer));
sw.WriteLine(sb.ToString());
sb = new System.Text.StringBuilder();

Quindi l'esempio di Robert Reid sarebbe diventato
using (var mailMessage = new MailMessage("[email protected]", "[email protected]", "subject", "body"))
{
//Add an attachment just for the sake of it
Attachment doc = new Attachment(@"filePath");
doc.ContentId = "doc";
mailMessage.Attachments.Add(doc);
var smtpClient = new SmtpClient("SmtpHost")
{
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network
};
// Apply credentials
smtpClient.Credentials = new NetworkCredential("smtpUsername", "smtpPassword");
// Send
smtpClient.SendAndSaveMessageToIMAP(mailMessage, "imap.mail.com", 993, "imapUsername", "imapPassword", "SENT");
}
Grazie per la tua risposta! Questa è sicuramente una considerazione probabile ora che è letteralmente solo la conferma che mi serve ... –
Il servizio di risposta di risposta di LachlanB sotto è la vera risposta. Questo è un po 'un trucco. – kenjara
