OT: Quick postfix question

I'm new to postfix, (making the transition from sendmail), and have a quick question.  In my main.cf, can I have multiple check_client_access lines?  Currently I have this one:
    check_client_access hash:/etc/postfix/rbl_override_whitelist
where I was whitelisting certain domains.  Then I realized I could also put in lines with REJECT rather than OK. 

It's largely cosmetic I suppose, as both REJECT and OK seem to work in the same file, but I'd rather have a whitelist and  a blacklist file similar to what we have in MailScanner, only at the MTA level.  Any issues doing that?
