No theoretical fixed limit, no.

If you want fast per-domain spam blacklist/whitelisting, use the per-domain
stuff in CustomConfig.pm.

If you want a straightforward spam blacklist that works very fast, look in
the latest CustomConfig.pm and search for "FastSpamList". That code isn't
quite what you want, but will be a very good starting point to implement it.
