Michael P.:

I periodically check my mail server IP on http://multirbl.valli.org/
and/or http://www.dnsbl.info/ , to make sure it's not on any blocklist.
(It was recently on one for cryptic reasons.  When I politely inquired
and stressed that I'd be glad to fix any problem but didn't understand
the existing one, the listing was removed without comment.)

$ host lists.balug.org
lists.balug.org has address
lists.balug.org has IPv6 address 2001:470:1f04:19e::2
lists.balug.org mail is handled by 100 mx.lists.balug.org.

http://multirbl.valli.org/lookup/  shows that one 
cluster of blocklists, the rfc-clueless.org one, doesn't like your IP.
This is the successor to Derek Balling's rfc-ignorant.org DNSBL, which
Derek eventually shut down, and has the same mission.  The listing
policy is here:  http://rfc-clueless.org/pages/listing_policy 

Looks like they believe that isn't accepting mail to
postmaster. an RFC requirement for any FQDN that deals in SMTP

When I did a quick check telneting to 25/tcp, it seems to me that the
system _was_ going to accept my manually composed mail to
postmaster@lists.balug.org -- so I'm unclear on why that listing's

Seems like they also have no-postmaster listings for FQDNs
balug-sf-lug-v2.balug.org, balug.org, and temp.balug.org. Maybe you
should actually cease accepting mail for those FQDNs.
