I also experience this. In the past, I've filed a support request with Microsoft asking for an explanation, but haven't received a satisfactory answer. An analysis of what I see shows: * no emails are sent, just a connect/STARTTLS/disconnect * the connecting IPs change Combined with when this started happening for me: * after I started blocking (at the SMTP level) selective spam emails originating from Microsoft's infrastructure Leads me to believe that these are health probes to try and check deliverability. I'm happy to be corrected/enlightened by more information. -- Alex _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
