I've upgraded postfix today and my openbsd to 3.5 snapshot version. Tonight I've requested a subnet but my postfix didn't run and sendmail had take its place, hence the mail sended by sixxs has been rejected as you could see : Mar 31 02:47:24 netw sendmail[23441]: i2V0lNwI023441: ruleset=check_rcpt, arg1=<djayweb@djayux.net>, relay=postfix@noc.sixxs.net [213 .197.29.32], reject=550 5.7.1 <djayweb@djayux.net>... Relaying denied Mar 31 02:47:24 netw sendmail[23441]: i2V0lNwI023441: from=<info@sixxs.net>, size=833, class=0, nrcpts=0, proto=ESMTP, daemon=MTA, re lay=postfix@noc.sixxs.net [213.197.29.32] ------------------------------------------------------------------------------- The problem come from a electrical failure, indeed all my machines was down for 10 minutes and on reboot the mail server don't work properly :/ So I would like to know if this is a problem ? Indeed the problem was solve now but maybe sixxs thinks that my mail address was false. It's my fault and now as bebru01 work fine, could I say bebru01 rox ? :), I hope sixxs continue to treat my subnet request.
