Seems your mail server is not sending the proper MAIL FROM or RCPT TO before the DATA command

I would trace the entire log of the message error or manually connect to another SMTP server from that server using the following:
---------------------------------

telnet othermailserver.com 25
helo mydomain
mail from: me@mydomain.com
rcpt to: you@othermailserver.com
data
Subject: testing
test
.
quit

---------------------------------
and  check if any errors return or whether the message goes through

This means you are not allowed to relay emails to your Cyberoam  mail server. On your mail server, you will need to give access to certain IP addresses for relaying e-mails and you should do the same for your specific IP as well.

Sorry, I was confused as to which mail server your were connecting to.

I now assume 203.196.139.146 is not your mail server but rather the recipient's; in that case, it seems they have some sort of antispam system running and it is detecting your emails as spam.

I checked to see if your domainname or IP is listed in any RBL list (http://www.robtex.com/rbl/) and it appears your IP is listed on one of these lists. Perhaps clearing your IP from this list should help.
