Perhaps it's just a typo, but you aren't allowing zone transfers from
209.16.228.146 in your named.conf file.
FW Rule: $fwcmd add allow all from 209.16.228.146 to $ns1
Named.conf:
allow-transfer { 209.16.228.140; //virtual/ns2
207.230.75.34; //ns1.deltacom.net
207.230.75.50; };

In a somewhat desperate attempt to convince my firewall to allow our
upstream provider to perform a zone transfer, I've added the following
line to the ipfw firewall.
$fwcmd add allow all from 209.16.228.146 to $ns1 keep-state in via
$oif
However, this is still not allowing a zone transfer. On occasion, the
secondary will write a file with a somewhat garbled name for the zone to
be transfered, but it is blank.
This firewall entry however, works.
$fwcmd add allow all from 209.16.228.146 to $ns1 in via $oif
$fwcmd add allow all from $ns1 to 209.16.228.146 out via $oif
Why doesn't the above dynamic rule work?
My rc.conf options section is as follows.
TIA,
