[Bug 70900] Re: Thunderbird uses a beep as notification

[Emmanuel Touzery]

for what it's worth i think thunderbird2 uses proper notifications on
linux too, although i'm not 100% sure. so i think that'll be fixed when
thunderbird2 is in ubuntu. for now we're at beta2, so it probably won't
make it in feisty...
