+* Thu Jan 18 2007 Warren Togami <wtogami@redhat.com> 
+- Options for RHEL4
+    * spamc/spamd cannot connect over IPv6 or SSL
+    * sa-update is disabled
+  The above functionality requires perl modules not included in RHEL4.
+  You may still use them if you get those perl modules from elsewhere.
+  RHEL5 ships these perl modules.
+
 * Thu Dec 14 2006 Warren Togami <wtogami@redhat.com> - 3.1.7-4
 - add standardized sa-update cron script, disabled by default
