How can I deal with the fraud warnings that are inserted into email messages by Office 365?
By Joshua DesPortes Sales Engineer, L-Soft
Office 365 customers who use LISTSERV have indicated that they have been receiving fraud warnings on certain email messages. The extra flagged text is added to the message by Office 365 on the receiving end when the "From" domain is the same as the receiving domain after passing through LISTSERV. Contrary to what Microsoft says in a blog post, this happens even with messages passing SPF and DMARC.
