(.NET Core C#) Secure IMAP over TLS/SSL

To communicate with an IMAP server over TLS/SSL, simply set the Ssl and Port properties. The remainder of your code is the same as with non-SSL.

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Imap imap = new Chilkat.Imap();

// To use a secure TLS/SSL connection, set the Ssl property and the port:
imap.Ssl = true;
// The typical port for IMAP SSL is 993
imap.Port = 993;

// Connect to an IMAP server.
bool success = imap.Connect("imap.someMailServer.com");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Login
success = imap.Login("myLogin","myPassword");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Select an IMAP mailbox
success = imap.SelectMailbox("Inbox");
if (success != true) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// We can choose to fetch UIDs or sequence numbers.
bool fetchUids = true;
// Get the message IDs of all the emails in the mailbox
Chilkat.MessageSet messageSet = imap.Search("ALL",fetchUids);
if (imap.LastMethodSuccess == false) {
    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Fetch the emails into a bundle object:
Chilkat.EmailBundle bundle = imap.FetchBundle(messageSet);
if (imap.LastMethodSuccess == false) {

    Debug.WriteLine(imap.LastErrorText);
    return;
}

// Loop over the bundle and display the FROM and SUBJECT of each.
int i = 0;
int numEmails = bundle.MessageCount;
while (i < numEmails) {
    Chilkat.Email email = bundle.GetEmail(i);
    Debug.WriteLine(email.From);
    Debug.WriteLine(email.Subject);
    Debug.WriteLine("--");

    i = i + 1;
}

// Disconnect from the IMAP server.
success = imap.Disconnect();
