Currently on my MX servers I use a custom rhsbl to reject domains

I am trying to create a list of spammer email ids so that I can reject
spammers of neutral domains. But this can be a potentially huge list.
I am not sure if this is a good idea.
If you're talking about the @domain.tld part of the Message-ID
header, it may be useful. There is a clever TCP based
header_checks program you can use for this.

If you're talking about the whole Message-ID header, probably
not, but more research would be needed. There would also be
the problem of looking up a domain with an '@' sign in it.
Will it be possible to reject
email ids via reject_rhsbl_sender.
No, reject_rhsbl_sender only works on the envelope address.
Use the checkdbl.pl header_checks instead.
Also how do I know the workable limits of maximum number of entries my
rbldnsd can handle.
Millions.
