in tx's tx.bgp4.net.mc:
define(`SMART_HOST', `nj.bgp4.net')

I'll have to go digging to find my notes on the issue, but I did a similar
thing with a FreeBSD secondary/Windows primary setup at my old workplace,
and had similar symptoms.  I was dealing with multiple domains, though,
and you are working within a single domain, which may be the difference
here.

For laughs, you could try putting the new version of sendmail on DragonFly
and see if it works "right".  That may be more pain than you feel like
enduring right now, though.
