grep jATBGtLN031461 `awk '/^mail\./ {print $2}' /etc/syslog.conf`

will provide more information.

To elaborate on what ynotssor is saying, the IP address on
the first "Received:" line, 203.198.86.99, is a reliable
indicator of the IP address from which your mail-receiving
computer received this message. Since 203.198.86.99 belongs
to netvigator.com, and since you are posting from netvigator.com,
the origin of the message may be revealed by looking for the
message-ID in your system's mail log files. You will probably
need root privileges to do so.

Personally I reject email from servers which HELO/EHLO themselves as
my mail server or with one of my IP addresses. They get a 5xy
rejection with a nasty text portion.

The same thing if the envelope MAIL FROM address is my current domain
registration email address or any of my past ones.
