I got a new server with a new
IP address. Apparently this
IP is listed in the hotmail blacklists so that I can't send mails to hotmail users out of my webapplication.
postfix/smtp[24706]: 8F31C9404B: to=<
[email protected]>, relay=mx3.hotmail.com[65.55.37.88]:25, delay=0.66, delays=0.01/0/0.48/0.16, dsn=5.0.0, status=bounced (host mx3.hotmail.com[65.55.37.88] said: 550 SC-001 Unfortunately, messages from 78.47.228.xxx weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. (in reply to MAIL FROM command))
My hoster will not help me get that address removed from the blacklist. So I tried to find a way to do it on my own, but I can't find a way to ask Microsoft to remove my
IP from that list.
Has anyone managed to remove a falsely listed address? And if yes: how?
