Mark, Since you said that newsgroups would allow non-members to post to the lists I have to assume that these newsgroups are open to the general public. Is this the case ? Some of my lists need to be kept private and can't be opened to the public (due to privacy and confidentiality laws). Is

Mark, This represents a serious potential risk. One of the problems I've noticed over the years with most Usenet groups is that they tend to attract a lot of spam and non-relevants posts. In this case, assuming I open the gate and allow posts from the Newsgroups to be posted to the list even b

My understanding is that DMARC alignment depends on both SPF and DKIM and that if a test using either protocol passes, then a DMARC will pass. This is probably an oversimplification, but I'm exploring the idea of whether it might be possible to interpose a milter using OpenDKIM (perhaps zdkimfilter

Hi, Mark. In the case you describe the server would send posts to the newsgroups and readers would access these newsgroups to see the posts. So posts are sent to the list using each list's e-mail address and then 'copied' to the newsserver. What happens when readers wish to reply to what they r
