Yes, many things are external to ones system and out of ones control.
And, yes, it may be problem...but it may only be a minor annoyance.

I know what you mean about being tarred with a brush. That is why I
used the term "good" RBL service. I know of at least one RBL service
that blacklists on a country basis. For those persons/companies
subscribing to that server my emails are blocked since I happen to live
in one of the "bad" countries.
FWIW, I'm not a fan of RBL services and while many of them exist I've
not seen any data as to how widely used they are.
