I ran a mail server I had in my home office that was hooked up to a cable service. Of the 50 people on the list, 20 could not send mail to the list -- even though they could receive mails. It turned out that all of them were using one cable vendor and were getting their internet connection through it. I tried calling them, but the technical support folk there said it was my problem and they were not interested in spending time trying to help me -- so I was on my own. I did a search on the problem at the time, and I wasn't the only person who ran into it. From my reading, it seemed that it was an issue of this particular ISP's internal security protocol that involved some sort of checking of ownership or something like that. The gist I got was that my domain resolved correctly, and the ICANN ownership info of the domain was correct, but the ownership of the some other component, like the IP address, was different, since it was tied to my ISP and not to me -- even though I was doing my own nameservice. Thus, I broke their spoofing rules. There was no solution that I could find, and none that worked for other folk who ran into it -- all of whom were running their own name and mail service from home. The workaround I ended up using was to change the Reply To: address for those users to a big-name server address (gmail as I remember) and then forwarded that to my server, which it would do. Note: 1) This was specific to one ISP (and the search turned it up only for that ISP) 2) It was back in 2008 3) I may not have characterized it correctly, since I didn't actually solve it. billo _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
