Hey all, Was just seeing if anyone has any Exchange experience that could help me. I don't do to much with exchange stuff, but I have a client that is on Office 365, and was getting hit with spoofers. So, we set up SPF, DKIM and DMARC. Which has worked great, but now we need to allow their web site hosting company send emails on their behalf. They are using word press, and it was coming from mail.wpengine.com. So, I added that to the SPF record, but the email still was flagged as spam. According to mxtoolbox, it passed SPF Alignment and Authentication, but failed both DKIM. So, they had me use SendGrid, which I verified the domain in SendGrid, and added the DKIM keys, and the CNAME for the return Path. This was still flagged as spam, showing that SPF Alignment and Authentication Failed, but DKIM Alignment passed. In the headers, it shows that SPF = Pass, so I am not sure what I am missing. The only thing I can think of is that MXToolbox is showing the Sendgrid and mail.wpengine.com IP as being blacklisted. Any help or a point in the right direction would be great.
