We use Xwall at a lot of our Exchange sites for anti-spam and are very happy with it. However many sites also have SonicWalls bundled with anti-spam. Is there any way we can make these two work together? I like the idea of doing 'off-LAN' anti-spam but the SonicWall product doesn't look as powerful as Xwall and I'm hoping to get a 'best of both worlds' combination. Again we use Exchange servers for our mail.
