I've traced the crash to the recipient domain - format string macros
'%r' (empty in spf addheader) and '%sr' (causes the crash). This does
happen with both racl and dacl rules, and the syslog debug entry for
the rule-hit contains the sender address among strings added by the
milter-greylist itself. Interestingly, the crash occurs (every time)
a couple of seconds after the message was fully received and processed
and logged. The message itself is not handed off back to the Messaging
Server and is not delivered into the mailbox.

I have used %r in other rules and it worked as expected...

So there a couple of things to do:
1) revise that domain/username format substrings do not crash with
empty input;
2) understand why the recipient is empty in this context?..
