Hard to imagine a usage case for such fine granularity. I would think:




forms would be sufficient.

Adding a 3rd level would hugely expand the number of lookups for each
RCPT. Typically for IPv4 and simple 2 label domains for sender and
recipient would 4 x 4 x 4 = 64 lookups, followed by the connect:to:
(avg. 16 lookups) and from:to: (avg. 16 lookups), then the to: (avg. 4
lookups) per given RCPT. And for IPv6 you go from 4 octets to 8 words.

It might be better to create a new tag syntax for RCPT that reduces the
lookups, while allowing the ability to match using a !glob! or /regex/
pattern list against a tuple string of "IP46 sender recipient".

	milter-link-rcpt:recipient	/ip46,sender,recipient/action ...


	milter-link-mail:sender		/ip46,sender/action ...

This could form a general basis for simplified and improved combo tags.
