RE: 'fraud detection checks' - resolved

Again, sorry to take everyone's bandwidth on this, but I would like to let = you know the resolution... Apparently, the text is being added by my outlook client because the messag= e is coming from an IP address (OSR's?) that doesn't match the SPF records = in DNS. The mail server sends the message 'as if' it was coming from "bob@r= amsystems.biz". Of coure the listserv's address is not in my SPF record. So, in theory, anyone using outlook should be seeing the "[This sender fail= ed our fraud detection checks..." on my messages. * Bob =A0 Bob Ammerman =A0 xxxxx@ramsystems.biz 716.864.8337 138 Liston St=20 Buffalo, NY 14223 www.ramsystems.biz > -----Original Message----- > From: xxxxx@lists.osr.com [mailto:bounce-622955- > xxxxx@lists.osr.com] On Behalf Of Robert Ammerman > Sent: Thursday, January 05, 2017 9:38 AM > To: Windows System Software Devs Interest List <xxxxx@lists.osr.com> > Subject: [ntdev] 'fraud detection checks' >=20 > [This sender failed our fraud detection checks and may not be who they ap= pear > to be.

RE: 'fraud detection checks' - resolved

<quote> So, in theory, anyone using outlook should be seeing the "[This sender fail= ed our fraud detection checks..." on my messages. </quote> I use Outlook (NOT Office 365) and I've never seen that message. Further, what you're seeing should not be the result of SPF checking... at least not SPF V1. SPF V1 doesn't use the "header sender address" (which would be xxxxx@ramsystems.biz) it uses the "enevelope sender address", which IIRC is set properly by Lyris. So... hmmmm.... Peter OSR @OSRDrivers
