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. Objective-C

#import <CkoImap.h>
#import <CkoMessageSet.h>
#import <CkoEmailBundle.h>
#import <CkoEmail.h>

BOOL success = NO;

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

CkoImap *imap = [[CkoImap alloc] init];

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

//  Connect to an IMAP server.
success = [imap Connect: @"imap.example.com"];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

//  Login
success = [imap Login: @"myLogin" password: @"myPassword"];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

//  Select an IMAP mailbox
success = [imap SelectMailbox: @"Inbox"];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

//  Get the message IDs of all the emails in the mailbox
BOOL fetchUids = YES;
CkoMessageSet *messageSet = [[CkoMessageSet alloc] init];
success = [imap QueryMbx: @"ALL" bUid: fetchUids msgSet: messageSet];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

//  Fetch the emails into a bundle object:
CkoEmailBundle *bundle = [[CkoEmailBundle alloc] init];
BOOL headersOnly = NO;
success = [imap FetchMsgSet: headersOnly msgSet: messageSet bundle: bundle];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

//  Loop over the bundle and display the FROM and SUBJECT of each.
CkoEmail *email = [[CkoEmail alloc] init];
int i = 0;
int numEmails = [bundle.MessageCount intValue];
while (i < numEmails) {
    [bundle EmailAt: [NSNumber numberWithInt: i] email: email];

    NSLog(@"%@",email.From);
    NSLog(@"%@",email.Subject);
    NSLog(@"%@",@"--");
    i = i + 1;
}

//  Disconnect from the IMAP server.
success = [imap Disconnect];
