Block TLD senders with opensmtpd

Hi all,

Looking at the manpage for smtpd.conf it's possible to block a domain with:

reject sender <table>

and put:

@domain.tld

Is it possible to block entire tld's and if so what would the syntax be?

I'd like to filter out high spam content senders ".bid, .date, .us" that I"m seeing and avoid spam processing altogether.

Thanks
Scott
