Rootsweb is based (with many changes of their own) on Mailman but Mailman itself has had at least 10 'significant' updates since the rootsweb version was set up. The latest Mailman does have reasonable (albeit imperfect because there is no perfect solution) aleviation of the effects of DMARC. > Earlier, items were sent without a "Reply-To" line.

Messing with the Reply-To header, and making messages anonymous, is a fudge to avoid the impact of Yahoo.com and AOL.com deciding that their customers email accounts should be made incompatible with the use of mailing lists. Many sites made such (anonymisation) changes a few months ago and many of those have updated their Mailman and re-emerged into a saner world. I'm presume rootsweb will do that eventually but they can't just upgrade, they have to re-fit all their changes. Meanwhile there is little choice but to grin and bear it. I'm bemused that some people think it's an imposition to expect them to sign their messages! = Malcolm. -- Malcolm Austen <malcolm.austen@weald.org.uk> GENUKI trustee <genuki@weald.org.uk> Pedigree User Group <chairman@pugweb.org.uk> Oxfordshire FHS <webmaster@ofhs.org.uk> FFHS Communications Officer <communications@ffhs.org.uk>
