I have enabled the feature in sendmail.mc to check with spamhaus for spammers. However since this block is being made at MTA level, I would like to know is something can be done to obtain statistics of blocked attemps.

I don't know what you mean, are you talking about stats for your machine, or more globally?

I use postfix; the logwatch report tells me who's blocked.

I have other rules too: ehlo <something> Something has to be present, resolvable and not a simple name. Stops lots (and some, but not many legit senders, and they get warned by their server if it's working)

The sender's IP must resolve to a domain name.

Those rules probably stop more than the block lists.
