I’ve been reporting a flood of new spammers operating out of Office365 to them. These are well known spam domains which have moved to Office365. MX and outbound mailers net handle records point to ab...@microsoft.com.
OrgAbuseHandle: MAC74-ARIN OrgAbuseName: Microsoft Abuse Contact OrgAbusePhone: +1-425-882-8080 OrgAbuseEmail: ab...@microsoft.com OrgAbuseRef: http://whois.arin.net/rest/poc/MAC74-ARIN They are refusing to take action, saying they don’t control the domains - which MX to office365 and deliver their spam from Office365 outbound mail servers. They are saying things like this back: > We recommend that you send your report to the postmaster at the domain that > is listed in the message header. For example, if the message came from > u...@xyz.com, forward the complete message to postmas...@xyz.com or > ab...@xyz.com. > > Sincerely, > > Patrick > Online Safety Team I’m blocking 64.4.0.0/18 on all MX targets now, aren’t you? -- Jo Rhett +1 (415) 999-1798 Skype: jorhett Net Consonance : net philanthropy to improve open source and internet projects.
