There is no way for me to test whether procmail-users requires posting from

This is not directly a problem with procmail-users. Your subscription
requests are never even making it to the mailing list. The SMTP server at
cuci.nl (the host of the procmail lists) is configured to reject mail from
domain names that it cannot resolve in DNS. This is a typical spam
prevention tactic -- spammers often report bogus domain names when
connecting via SMTP.
I'd guess that this is most likely to be some kind of anomaly with
cuci.nl's DNS lookups, but the problem _may_ be this (from an "nslookup"
session):
----------
server ns.nara.kindai.ac.jp
Default Server: ns.nara.kindai.ac.jp
Address: 163.51.101.70
irm.nara.kindai.ac.jp
Server: ns.nara.kindai.ac.jp
Address: 163.51.101.70
Non-authoritative answer:
irm.nara.kindai.ac.jp preference = 10, mail exchanger =
ns.nara.kindai.ac.jp
irm.nara.kindai.ac.jp internet address = 163.51.101.70
irm.nara.kindai.ac.jp nameserver = ns.nara.kindai.ac.jp
irm.nara.kindai.ac.jp
origin = ns.nara.kindai.ac.jp
mail addr = postmaster.nara.kindai.ac.jp
serial = 2001102402
refresh = 3600 (1H)
retry = 300 (5M)
expire = 3600000 (5w6d16h)
minimum ttl = 86400 (1D)
Authoritative answers can be found from:
ns.nara.kindai.ac.jp internet address = 163.51.101.70
----------
Note that ns.nara.kindai.ac.jp is supposed to be the authoritative server
for irm.nara.kindai.ac.jp, but it gives only a non-authoritative response.
If ns.nara.kindai.ac.jp is within your control, you need to fix its DNS
configuration so that it produces authoritative responses. If that server
is the one about which you can't "rock the boat," then I'm afraid you're
simply up the river without a paddle.
