Corrupted headers in received messages

Corrupted headers in received messages

Hi. In the past two days I have received several messages that do not display correctly in the Zoho webmail client. The messages have no subject and the To and From fields are missing. In the message body you can see various lines from the message header.

I have tried to investigate what is wrong using Thunderbird as an IMAP client. The message I examined contained an unwanted blank line in the middle of the headers. This caused the message to be displayed incorrectly.

The blank line was between the lines shown below 

 X-Zoho-Virus-Status: 2 

 X-Received: (qmail 55492 invoked from network); 16 Aug 2012 17:46:12 -0000


Could you please check what is happening. Regards, Bob
