Hi,
since days, we try to find out why one of our customer domain is blocked, when sending mails to remote sites, where Sophos UTM-appliance (e.g. UTM-430) are in place. All we see is at smtp level: <john....@famo24.de>: host mail3.famo24.de[80.155.146.58] said: 550 Administrative prohibition (in reply to end of DATA command) Recipients (admins) confirm, that according to local FW logs, they see 'confirmed spam'. All of our sending IPs are in no blacklist nor have been over the last years. I checked all the known blacklists. Even cyrens own site. All is green and good. One of our sending IPs is 116.203.31.6 Anyone with an idea? Thank you. Stefan
