I've been running a postfix for years (since 2008ish) and never once checked or worried about blacklists. My 3 users haven't reported any problems at all.

What if they missed emails they never knew about in the first place? What if they tried to contact someone and just assumed they've been ignored? Unless you know you're not on blacklists, you should be worried at least a bit.
