I just published YUM updates for 5210R that introduce this change to
Postfix:

smtpd_sender_restrictions is set to either ...

postconf -e 'smtpd_sender_restrictions = permit_mynetworks,
check_sender_access hash:/etc/postfix/access'

... or ...

postconf -e 'smtpd_sender_restrictions = permit_mynetworks,
reject_unknown_sender_domain, reject_non_fqdn_sender,
reject_non_fqdn_hostname, reject_unknown_reverse_client_hostname,
reject_unknown_client_hostname, check_sender_access
hash:/etc/postfix/access'

... depending if "Accept from unresolvable domains" is enabled or
disabled in the GUI.

The second set of parameters is the new default. Means: We do strict
checking.

Additionally a new script was added:

/usr/sausalito/bin/custom-postfix-confgen.sh

This script will never be changed during YUM updates and you can put
into it your own "postconf -e" config changes to Postfix. These will be
executed automatically on Postfix restarts *after* the GUI has finished
its auto-configuration of Postfix.

Essentially /usr/sausalito/bin/custom-postfix-confgen.sh allows you to
reconfigure Postfix entirely - if you wish. So use it with caution. An
example is included in the script itself.
