Of course it can! Blackberry isn't the only email game in town!
Out of the box, the N95 has the same pull email option as all s60 devices which works well if you don't need your email the second someone sends it to you.
There are some claims that the Blackberry Connect application works with the N95 as well for push email, but I haven't heard or seen anybody set it up as of it.
There's also emoze, which syncs your emails FASTER than Outlook can grab them, which is nifty. The member "Zeze" has a blog about s60 applications and he wrote a fantastic review about it if you'd like to learn more about it. I haven't tried it myself because I'm still trying to make the transition from Thunderbird and my PC is still waiting to be formatted.
