[arch-general] DKIM signed messages to mailing list - issue

Each time I send to the arch list I get a postmaster complaint about DKIM from postmaster@bctpe4hbiu.org My domain DKIM signs all mail - however my DKIM signature is passed through by the mail list package and of course now the message will fail DKIM check as the header has been modified and is no longer coming from my domain. I guess the list should remove incoming DKIM headers? gene
