Hi guys, been testing our email delivery as open rates neeb declining and noticed that report shows IP’s being
flagged up with hotmail/outlook/ etc.
So they all show some listings, but of course the first one relating to Exchange that covers I believe hotmail/outlook and MSN? so this is big hit like 20% or so of emails got restricted because of this dynamic IP sharing I’d guess.
and this is another pair of IPs that shows up as on spam lists with hotmail/outlook:
Spam Received Recently See: SORBS Database Lookup
Looks like entire IP ranges been under some sort of issues.
