[boost] Posts not appearing on Boost Mailman

Hi Boost, I have an issue with MailMan: I never use "emails" for posting on the Boost ML, I use news.gmane.org through thunderbird. I can see my posts on news.gmane.org, but I cannot see any of my posts here for instance: https://lists.boost.org/Archives/boost/2017/07/index.php Is this normal? Thanks, Raffi
