I do that here (have a local copy of the zones, for sendmail and SA to 
query against).

I recall having to restart some things to get them to notice that the 
resolv.conf had changed.  I seem to recall this is more of a problem 
with sendmail ... but it may depend on how you're calling spam assassin. 
  If you call if via procmail, I wouldn't expect it to be an issue.

When we first did this, we were running mailscanner, and I don't recall 
having to restart it.  When we moved from mailscanner to mimedefang, I 
don't think we had to restart that either.  But we definitely had to 
restart sendmail (it caches the resolv.conf at start up, and, IIRC, 
never reads it again, so changes aren't recognized without a restart).

If you're using a milter, try restarting the milter.

Worst case, try rebooting.
