I opened a bug: https://issues.apache.org/SpamAssassin/show_bug.cgi?id=7054
because I thought that this is something fairly common that the core module could do on behalf of plugins rather than having the modules (a) duplicate the functionality, possibly getting it wrong, and (b) generate a lot of unnecessary traffic as each plugin does its own separate lookup (since they have no way to share a cache within SA itself). I think this could be done in a way that is backward compatible with other modules, and would simplify URIDNSBL.pm significantly. When is the next release of SA (3.5.0?) due out? Thanks, -Philip
