Hi Team,
IP addresses of the Microsoft O365 blacklisted by Polspam BL, Polspam RHSBL, Polspam RHSBL-H, Rymsho's RHSBL, Spam Grouper Net block list, Hostkarma, Abusix Mail Intelligence Whitelist, SPFBL.net Whitelist.
Please, note that our company O365 IP addresses are blocked, not external client.
Could you, please, tell me of how to engage Microsoft to de-list IP addresses they provide?
Regards,
Serge
