In Postfix 2.10 Snapshot 20121022, conf/post-install tests whether smtpd_relay_restrictions is already set with:
test -n "`$POSTCONF -c $config_directory -nh smtpd_relay_restrictions`" This evaluates to false when smtpd_relay_restrictions is explicitly set to the empty value in main.cf, resulting in the parameter being overriden as described in RELEASE_NOTES. This seems inconsistent with my (perhaps faulty) interpretation of intended behavior. Would it make more sense to revise the above test to: test -n "`$POSTCONF -c $config_directory -n smtpd_relay_restrictions`" With this, the forward compatibility shim would only trigger if smtpd_relay_restrictions does not appear in an existing main.cf, while explicitly empty settings of the parameter would be preserved during an upgrade. Sorry if I have misunderstood something; I just want to be clear on how this works before updating the FreeBSD port. -- Sahil Tandon
