We've been seeing runs of spam mails from Microsoft IP addresses without
reverse DNS (possibly cloud servers).
One is sending with addresses <pharmacy@*>, starting on February 8.
The other (same or different spammer?) uses <ne-pas-repondre-*@*> and started
just yesterday.
Have others seen these? Is there some way to identify the host IPs which are used by those cloud servers, so one could
block incoming SMTP from them if Microsoft can't be bothered to block outgoing SMTP?
Cheers,
Hans-Martin
