MailCore 2 provide a simple and asynchronous API to work with e-mail protocols IMAP, POP and SMTP.

Hello

i am getting error : "Unable to parse response from server."

But when i remove following file: scripts/prebuilt.lists

it is working fine.

Everytime i have to remove this file and buil again?

Please do help.

I'm creating a pull request so it's easier to discuss and track changes as opposed to in the issues themselves.

As discussed in #112 and #111, this is a first pass at defining the interface. Currently only includes IMAP. RFC 822 to come.

I need to look further into the implementation and how the existing IMAPMessage::htmlRendering and HTMLRenderer::htmlForIMAPMessage methods work. It's unclear to me at this point if these new methods need to take additional parameters for the callbacks or if callbacks will be created within their implementation.

I'm hesitant to discuss here due to the NDA.

I'm happy to use Apple forums or whatever is preferred but the issue is easily reproducible for me by following the standard steps.

Hi,

1. I have followed the instructions to build the AndroidExample App. Build successful. I tried to do run Android Example with .aar file in libs folder. I have changed MessageSyncManger with username,password,host and port number.

    session.setUsername("[email protected]");
    session.setPassword("mypassword");
    session.setHostname("imap.gmail.com");
    session.setPort(993);
    session.setConnectionType(ConnectionType.ConnectionTypeTLS);

I am getting following error and app crashes. /com.libmailcore.androidexample A/libc﹕ Fatal signal 11 (SIGSEGV), code 2, fault addr 0x766e6f6f in tid 13683 (.androidexample)

How can i fix this issue.

2. The minimum sdk for the AndroidExample App and .aar Libary Project is set to 21.

if i change the minimum sdk in the app/build.grade file to 14 then

Error:Execution failed for task ':app:processDebugManifest'.

Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 21 declared in library C:\Users\pratap\Desktop\mailcore2-master\example\android\AndroidExample\app\build\intermediates\exploded-aar\mailcore2-android-1\AndroidManifest.xml Suggestion: use tools:overrideLibrary="com.libmailcore.library" to force usage

is MailCore2 does not support lower than Lollypop devices ?

3. I Found LoginActivity in the AndroidManifest.xml file but i did not found Activity java file.

Thanks, Pratap.

If i try to login Outlook , it ends up with the below error.

Error Domain=MCOErrorDomain Code=1 "A stable connection to the server could not be established." UserInfo={NSLocalizedDescription=A stable connection to the server could not be established.}

I am using below code,

session = [[MCOIMAPSession alloc]init];
session.hostname = @"mail.outlook.com";
session.username = userName;
session.password = pwd;
session.port = 993;
session.authType = MCOAuthTypeSASLPlain;
session.connectionType = MCOConnectionTypeTLS;

Any help would be appreciated..

Although I am successfully able to fetch folders and messages for my Outlook email accounts, I discovered that I am unable to send messages.

When I first encountered the problem, I went into the terminal and tried to connect to the server by doing:

openssl s_client -starttls smtp -crlf -connect smtp-mail.outlook.com:587

This was successful. My smtp session settings matched the above request:

self.smtpSession = [[MCOSMTPSession alloc] init]; self.smtpSession.hostname = smtp-mail.outlook.com; self.smtpSession.port = 587; self.smtpSession.username = [email protected]; self.smtpSession.connectionType = MCOConnectionTypeStartTLS; self.smtpSession.password = nil; self.smtpSession.OAuth2Token = (same token as is working for imap session); self.smtpSession.authType MCOAuthTypeXOAuth2; self.smtpSession.checkCertificateEnabled = NO;

The first error I received was:

2014-03-12 16:49:01.107 MailApp[9748:60b] sendOutboxEmail error:Unable to authenticate with the current session's credentials.

Next, I tried changing the smtpSession.connectionType to MCOConnectionTypeTLS. This change yielded a different error:

2014-03-12 16:44:01.049 MailApp[9531:99cf] CFNetwork SSLHandshake failed (-9800) 2014-03-12 16:44:03.610 MailApp[9531:60b] sendOutboxEmail error:A stable connection to the server could not be established.

My smtp session connection logger for the first attempt using the startTLS connection printed:

Do you have any thoughts on why this might be happening? Thanks.

When I use pod spec lint, I get the following error:

 -> mailcore2 (0.4.5)
    - ERROR | [iOS] The `preserve_paths` pattern did not match any file.

The layout of the zip file is:

mailcore2-ios-5/include/MailCore/*.h
mailcore2-ios-5/lib/libMailCore-ios.a

If I prefix the pattern with mailcore2-ios-5, it will go through the lint. Though, when I include mailcore2 in a Podfile, the library and the header files won't show up in the resulting project folder.

Is there anything I'm missing?

Thanks!

@dinhviethoa I'm observing the same issue as described in #665 on the latest code. This behaviour seem to occur only on corporate Gmail accounts.

I have a MCOImapSession on a singleton, called every 5mins to execute MCOImapSearchOperation.

Putting some breakpoints, it seems to stuck on MCImapSession.cc line num:641 "r = mailimap_ssl_connect_voip(mImap, MCUTF8(mHostname), mPort, isVoIPEnabled());" and does not proceed to next line on succeeding calls. (1st execution will go through).

Many thanks!

When are you guys going to just release this as a framework for iOS? Is there some technical limitation stopping you?

The need for me comes from a lot of trouble getting mailcore2 integrated into my project. Following the directions I found didn't work. With a lot of tweaking it's in there, but unfortunately it's not in as a separate library - it builds every time and runs those scripts.

Hi, i'm quite new to MailCore 2 and im having trouble fetching emails from yahoo & hotmail accounts. I can fetch gmail emails with no problem.

Yahoo:

When I try to fetch email from a yahoo account (imap.mail.yahoo.com) I get the following Error:

Error Domain=MCOErrorDomain Code=1 "The operation couldn’t be completed. (MCOErrorDomain error 1.)

I couldn't seem to find a list of error codes so i dont know what this error code means.

With Hotmail accounts you have to use POP3 but i couldn't find a example of how you would fetch emails. I've tried the following Code:

    self.popSession = [[MCOPOPSession alloc] init];
self.popSession.hostname = hostname;
self.popSession.port = [port integerValue];
self.popSession.username = username;
self.popSession.password = password;
self.popSession.connectionType = MCOConnectionTypeTLS;

NSLog(@"checking account");


    self.popMessagesFetchOp = [self.popSession fetchMessagesOperation];

    [self.popMessagesFetchOp start:^(NSError *error, NSArray *message ){

     NSLog(@"Error:%@", [error localizedDescription]);
     NSLog(@"POP3 Message Array: %@",message);

}];

I don't receive any errors in the console just a NULL array.

Any help would be much appreciated!

I'm try to use the mailcore2 library with an iPad app. When I try to send an email I get the "Unable to authenticate with the current session's credentials" error.

We use an open replay for our exchange server. Is there a way to prevent it sending a username and password as I think this maybe the issue?

Hi,

I use your library with my mail client, Mailspring, on MacOS and Linux, and it appears that the method used to check if the SMTP server is valid (SMTPSession::checkAccount), is trying to send an email at "[email protected]".

https://github.com/MailCore/mailcore2/blob/a23882b13a1028753d1bdaef795cfd91acd7be8c/src/core/smtp/MCSMTPSession.cpp#L680

The problem is that some SMTP servers are responding with an error because the domain "invalid.com" doesn't actually exists. This causes the checkAccount method to fail even though the connection with the server is working fine.

SMTP Last Response Code: 450
SMTP Last Response: 4.1.2 <[email protected]>: Recipient address rejected: Domain not found

Thanks in advance for your response. Maxime

Hello the iOS MailCore don't being able to find MCOIMAPMoveMessagesOperation.h file when using CocoaPods and 'MCOSMTPSendOperation' callback not responding when using Carthage. I use XCode version: 14.0

            }else {

            }
        }];
        complete();
    }
}];

Here is the chunk code I have used, It works if the folders are other than [Gmail]/important.

IMAPFolderQueue = OperationQueue() IMAPFolderQueue?.name = IMAPFolderQueuesNames.storeLabelsOperation.name() IMAPFolderQueue?.qualityOfService = .background let storeLabelsOperationQ = BlockOperation() let semaphore = DispatchSemaphore(value: 0)

    let uidSet =  MCOIndexSet()
    for uid in uids {
        uidSet.add(MCOIndexSet(index: UInt64(uid)))
    }

    storeLabelsOperationQ.addExecutionBlock {
        let storeLabelsOperation = self.mailCoreIMAPSession?.storeLabelsOperation(withFolder: folderPath, uids: uidSet, kind: kind, labels: labels)
        storeLabelsOperation?.start({ (error) in
            guard error == nil else {
                semaphore.signal()
                return
            }
            semaphore.signal()
            status = true
            return
        })
        semaphore.wait()
    }
    storeLabelsOperationQ.completionBlock = {
        getCompleted(status)
    }
    IMAPFolderQueue?.addOperation(storeLabelsOperationQ)

Thanks in advance !

Fixing #1785 pthread_mutex_t was chosen because

1. it's already using on some platforms
2. os_unfair_lock must be allocated on the heap so it couldn't be used as c++ class member (Concurrent Programming With GCD in Swift 3 or SO)

Summary In the past couple of weeks we started to observe that using Mailcore2 we don't get the extra headers anymore for any of the messages on Yahoo and Aol.

This is working fine using MailKit (Windows version). It happens on all phones all accounts so I think others encountered with this as well.
