Hi Guys,
Lately its appear that our company can't email to the Hotmail/outlook users
all the emails are bounced back with the error !
Remote Server returned '< #5.5.0 smtp;550 SC-002 (COL004-MC6F27) Unfortunately, messages from 195.121.247.4 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.>'
any suggestions who to contact about this ?
thank you
