Hi, I have setup a postfix mail receiving server and deployed DKIM and SID+SPF milter by referring (http://www.postfix.org/MILTER_README.html).
Now things are working fine but at times some of the mails that are received on my postfix are rejected with error code 550 and they receive a message like 'bad DKIM signature data (state 18)'. e.g.: someone who sent a mail with blank body and no attachment to my postfix received the above message on his gmail account. What is this problem about, any clues? Thanks in advance Ashish Sharma
