Date incorrect in Hotmail IMAP Append

[ashish1405]

  In Hotmail (imap-mail.outlook.com), the APPEND command uses OPTIONAL date/time string argument instead of Date: header, for setting message date.

This argument can never be set in the MailCore2 API because the date parameter is passed as NULL in IMAPSession::appendMessageWithCustomFlags

r = mailimap_uidplus_append(mImap, MCUTF8(folder), flag_list, NULL, messageData->bytes(), messageData->length(),
        &uidvalidity, &uidresult);

Because of this what ever date is set in [[builder header] setReceivedDate:date]; [[builder header] setDate:date]; in append command, Hotmail takes the current date/time.

Does hotmail accept an empty date?

[ashish1405]

As an argument or as Date: header?

[dinhvh]

Is it an issue for hotmail if the date value is NULL here?

r = mailimap_uidplus_append(mImap, MCUTF8(folder), flag_list, NULL, messageData->bytes(), messageData->length(),
        &uidvalidity, &uidresult);

[ashish1405]

Yes because that variable is used in libetpan as date argument.

ok. Could you show the connection logger logs when you try to append a message to hotmail?
Thanks.

So it works. Why would you need to customize the append date of the appended message?

[ashish1405]

My application is for backing up old messages. So I need to have past dates.
What ever the date we set in [[builder header] setReceivedDate:date]; [[builder header] setDate:date]; that date is not set in hotmail mail. It uses current date. So if we set a past date that is not set. But from command line using openssl if I set the date in APPEND parameter like below it works properly.

$ openssl s_client -crlf -connect imap-mail.outlook.com:993
...
...
tag login user@hotmail.com password
tag APPEND inbox (\Seen) "10-10-2013 10:10 -05:00" {310}
Date: Mon, 7 Feb 2014 21:52:25 -0800 (PST)
...
...

As seen above, the append argument (in same line) has a date, Hotmail uses that date and not the date set in Date: header

Add a date property to MCOIMAPAppendMessageOperation.

[ashish1405]

Ok, And how will I access this property in MCIMAPSestion::appendMessageWithCustomFlags?
