Are you sure it wasn't mx1.freebsd.org?  And are you mangling 
my.mywebsite.com or is that really the hostname with which your server is 
configured to EHLO/HELO?  The FreeBSD MXs also run Postfix and employ the 
reject_unknown_helo_hostname restriction; it rejects HELO and EHLO hostnames 
that lack DNS A or MX records.  Your log excerpt looks suspicious because 
my.mywebsite.com does have a valid DNS A record:   

	my.mywebsite.com.	96	IN	A	208.87.33.150

It is actually Postfix behind the scenes!  See man mailwrapper(8) and the 
contents of /etc/mail/mailer.conf.
