I've been using the Chilkat library for several years in some of my projects (iOS and OS X). Recently I needed to update some of them, so I also updated the Chilkat library. However, with the updated Chilkat library (both SMTP and IMAP) it seems impossible to connect using SSL.

Here's the test code:

  • (void)testConnection {

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

    BOOL success;

    success = [imap UnlockComponent: @"Anything for 30-day trial"];

    if (success != YES) {

    NSLog(@"%@",imap.LastErrorText);
    
    return;
    

    }

    imap.AutoFix = NO;

    imap.Port = [NSNumber numberWithInteger:993];

    imap.Ssl = YES;

    imap.StartTls = NO;

    imap.SslProtocol = @"default"; // Tried all possible options

    //  Connect to an IMAP server.
    

    success = [imap Connect: @"mail.lekkerthuis.biz"];

    if (success != YES) {

    NSLog(@"%@",imap.LastErrorText);
    
    return;
    

    }

    //  Login (never gets here)
    

    success = [imap Login: @"MeAndMyself" password: @"myPassword"];

    if (success != YES) {

    NSLog(@"%@",imap.LastErrorText);
    
    return;
    

    }

}


It fails with:

If I link the project with the 2012-version of the Chilkat library, it works fine.
