@dinhviethoa @CodaFi Hello! Now please help me, what is wrong with this following response from server as i am again getting "Unable to parse response from server" error:

Hi, I also run into this problem "Unable to parse response from server.", the app crashed; it happened in the middle of downloading a mail box with a lot of mails. I try to get the plainTextBodyRendering for each email and display a summary or list view. If I replace the fetchMessagesByUIDOperationWithFolder (with MCOIMAPMessagesRequestKindStructure flag set) with fetchMessageByUIDOperationWithFolder, the download becomes very slow. Is there a way to just skip that offending email, or a way to handle the error gracefully, or other work around? Thanks.

[Pankaj03]

Can you share some error logs? Try to fetch the message without passing BODYSTRUCTURE as requestkind.

[denniscyoung]

It works fine if i don't set BODYSTRUCTURE as requestkind in the fetchMessagesByUIDOperationWithFolder. The problem is that the work around of using fetchMessageByUIDOperationWithFolder becomes very slow as i am downloading a lot of mails and want to show plainTextBodyRendering in the summary view.

[Pankaj03]

Instead of setting BODYSTRUCTURE, fetch full content of message using MCOIMAPFetchContentOperation. For performance issue, get the message headers first and call asynchronous for full content.

[denniscyoung]

Hi Pankaj03, thanks for the suggestion, i tried that, in my situation fetching the full content is too slow. I don't mind skipping the offending mail, is there a way to do that or some other error handling?

[Pankaj03]

Can you show some error logs?

[Pankaj03]

I need complete error log, means whole response.

[denniscyoung]

I already turned on MCLogEnabled = 1 in MCLog.c. Is there another flag that shows the whole response? This is happening inside the MCOIMAPFetchMessagesOperation for fetchMessagesByUIDOperationWithFolder, with requestKind = (MCOIMAPMessagesRequestKindHeaders | MCOIMAPMessagesRequestKindStructure | MCOIMAPMessagesRequestKindInternalDate | MCOIMAPMessagesRequestKindHeaderSubject | MCOIMAPMessagesRequestKindFlags);

[Pankaj03]

Try by adding following code:

[self.imapSession setConnectionLogger:^(void * connectionID, MCOConnectionLogType type, NSData * data) { NSString *setConnectionLoggerStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@"ConnectionLogger event logged: %i withData: %@", type, setConnectionLoggerStr); }];

and provide the console log.

[denniscyoung]

i added the code setConnectionLogger, but i don't see much difference or new data, here's the log:

It looks like your server is failing:

* Internal error writing data

[dinhvh]

Which server is it?

[denniscyoung]

Yahoo (imap.mail.yahoo.com). When this happens, is there a graceful way to handle it such that i can get whatever has been downloaded, or just skip it?
