Hi, My mailserver's log is filling with : Jul 31 16:13:33 mail postfix/smtpd[7244]: NOQUEUE: reject: RCPT from ip-70-38-54-91.static.privatedns.com[70.38.54.91]: 450 4.7.1 <www.localdomain>: Helo command rejected: Host not found; from=<gluster-users-bounces at gluster.org> to=<julien at cornuwel.net> proto=ESMTP helo=<www.localdomain> I don't if it comes from the ML or a user's mailserver, but someone has a strange config. I hope he will see this and fix his conf. Regards,
