I am having a large (20%) of messages fail dkim. If I do some random checks, it looks like most of the failing messages are from the outlook.com cloud. Does any one else have this? Or is my setup just not properly checking dkim of outlook.com?
how should i guess ?i see o365 not dkim sign at all, this is ok when spf pass, but not often spf_helo fails, should dmarc care of spf_helo ? :)
more help needs more info from you
