I've had a few reports of select users posts not getting out to all
servers, and experienced it myself in a group last night, running one
of my scripts that checks open servers, verified my suspicions, there
seems to be something in the cleanfead script inn servers not liking
(all?) ipv6 addresses.

resend, wait an hour then resend removing only ipv6 address, they
reported back to me this morning there ipv6-less messages can be seen
on the inn based servers.

perhaps its not all address es that trigger this.

day dot, I'm suspecting since the peers who accepted it, do binaries,
it might be in the detection of such messages, and is misclassifying
ipv6 addresses - but as not an inn operator, I'm only guessing.

Since I don't peer with you, and unless you peer with a few binary services, you wont have any log records so MID's will be useless.
This is just a heads up and anyone who knows inn's cleanfeed rule detection, might see where it happens, I've advised my people and users to not use ipv6 addresses in usenet.
I have a test script I wrote years ago to disprove to others our server was eating their posts, it comes in handy for uses like this too, it checks 10 or 11 open servers and  only ours had the article, as I'm away for 10 days I can really run it and paste the outputs.
