I use nntp.aioe.org NNTP server. It seems that this server does not accept supersede articles. When I send a supersede article and a regular article afterwards, it seems that the supersede article blocks the queue and not only it is not delivered but also any messages after it in the queue. Workaround: Delete supersede articles from the queue. Reproducible: Always
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug.
