While reading mail message i need to have Mail send Date and Time, but while reading Mail Message object the "Date" property is not giving Time/Timezone.

Ex: I have send an email from Yahoo (IST) to Gmail. the Date and Received Date properties values are like below:

Local Time : 06/18/2015 09:26:30;
OriginalTime: 06/18/2015 13:26:30;
UniversalTime: 06/18/2015 13:26:30;
TimeZone: 00:00:00

Date Local Time : 06/18/2015 09:26:30;
OriginalTime: 06/18/2015 08:26:30;
UniversalTime: 06/18/2015 13:26:30;
TimeZone: -05:00:00

For Date the TimeZone is 00:00:00

In my project i used to show client mail send date & time.

How to resolve this one? Is this Yahoo mail server issue or Rebex?

Thank you,

This looks like Yahoo mail server issue . A Stack Overflow question IMAP date filter issue seems to describe what might be a related issue with Yahoo and IMAP.

Could you please download the message directly into a file using Imap.GetMessage method (this is important - don't download into MailMessage/MimeMessage and then save) method, open it using a text editor such as Notepad and copy&paster the Date: and Received: headers here? That will make it possible to tell whether this is an IMAP server or client issue.

Hi, thanks for quick response.
I have sent an email from Yahoo at IST  @9.26 pm.

Here i did like saved the file in D drive as like below:

 //get all messages
            messages = imap.Search(ImapListFields.Fast, ImapSearchParameter.Unread);
           if (messages.Count > 0)
                foreach (ImapMessageInfo itemInfo in messages)
                    imap.GetMessage(itemInfo.SequenceNumber, "D://test.txt");

And the result is:

This confirms that it's indeed Yahoo that seems to be using a UTC timezone +0000 for all their headers in this case. There is nothing we can do about that, unfortunately - we just parse what we get. Perhaps changing the time zone in Yahoo would help? https://answers.yahoo.com/question/index?qid=20081220235849AAmlxde
