I wanted to know if there is a good place to check if the domains were blacklisted by search engines.

I don't know of any such lists and, for legal reasons, I doubt search engines would make such information available.
There are some lists available for e-mail spammers (e.g., like here). When an e-mail spammer sends to "trap" e-mail addresses or they get flagged by users, they sometimes get automatically added to such lists. Yahoo and Google probably maintain their own private list of e-mail spammers that they may match to web domains.
