I'm very happy to say that this great 'mailplugin' also works fine on PPC Macs!!!

I've just installed version 0.22, since I'm running Mac OS 10.5 on a PowerMac G5.

-Installation on PPC Mac running 10.5 without any problems!
-First launch of the Mail app and everything works just fine!
-Preferences are all working!
-Auto Update works also!
-In short, everything works just fine like it should be! On both architectures :-) ...

To the developer: Could you please correct the requirements from Intel to PPC/Intel.

You've made a lot of PPC users very happy with this mailplugin!!!

I'll write a complete 'review' when I used the plugin a couple of months. But for now 5 stars!!!

With kind regards.
