MacOS – Writing emails in different languages in Mail.app

On Mac OS X Snow Leopard (and maybe Leopard), the spell checker is smart enough to detect which language you're using.

Well, YMMV, personally I'm mostly writing in French and English, and I just have to type the 4 ou 5 first word, and Mac OS X automatically detect which language I'm using.

It seems to detect at least by paragraph, but it could also be by sentence, I haven't fully tested.

So try to set your spell checker language to "Detect automatically" and see if it's smart enough for your use.

You need to update your rules to move mail to the gmail IMAP folders rather than the ones from 'On My Mac'. When it does that, it is copying them out of the gmail box to your local mail store.

You could also have the rules set up in gmail which will parse them before sending mail to your device, so on both your Mac and iOS devices they would already be in the correct location.
