One quick thing you can check is your /etc/mail/mailer.conf:

# Execute the Postfix sendmail program, named /usr/local/sbin/sendmail
#
sendmail	 /usr/local/sbin/sendmail
send-mail	 /usr/local/sbin/sendmail
mailq	 /usr/local/sbin/sendmail
newaliases /usr/local/sbin/sendmail

I've had this happen before when I did a system rebuild and the original 
system based sendmail became used again instead of the Postfix install. If 
this file got reset back to pointing at the system sendmail somehow you will 
see these errors. IIRC Postfix has a switch which selects where it gets 
installed. Perhaps the upgrade didn't put it back where it originally was 
located, in which case you are again executing the sendmail binary instead 
of the mail getting picked up by Postfix.

This is what my current /etc/rc.conf looks like:

#sendmail_enable="NONE"
postfix_enable="YES"
sendmail_enable="NO"
#sendmail_flags="-bd"
#sendmail_pidfile="/var/spool/postfix/pid/master.pid"
#sendmail_procname="/usr/local/libexec/postfix/master"
sendmail_outbound_enable="NO"
sendmail_submit_enable="NO"
sendmail_msp_queue_enable="NO"

Also, if you are using sasl auth you might try rebuilding that as well. You 
might get more info looking in the /var/log/maillog too.

Just a few quickies off the top of my head to get started with...
