Unable to post to newsgroups
I have tried using a range of newsreaders on Slack 9.0 (Pan, KNode, Mozilla) and am still unable to post anything to newsgroups. I can read news just fine but given the range of readers I have attempted to use to post the one commonality is my system.
I can send and receive email just fine, so my email settings are fine. I am using a standalone box behind an iptables firewall using dial-up. My ISP assures me that their settings are fine and I have used their info to set up each of the readers but still to no avail.
I am not even sure where to begin to hunt down info on this, so am asking for some clues or suggestions as to where to begin to resolve this.
