I have a postfix mail server used in conjunction with Maia Mailguard, Amavis, and clamav for spam. I've upgraded the primary mail server and it has a new IP address. I change main.cf and transport to point to the new server 172.17.2.9 in /etc/postfix, then reload postfix. When I look in /var/log/mail.log, "postfix/smtp * relay=172.17.2.15[172.17.2.15]:25 is still the old mail server (172.17.2.15).
postconf -n with our actual domain changed to mydomain.com

I've checked resolve.conf and the hosts file to make sure there's nothing funny going on in there, all looks fine.
I've reviewed the maia config.php file and the maia.conf file, nothing there.
Where else could the old server IP be set for mail flow?
