I've got a friend with a server hosted by ServInt in the states which facilitates a few email accounts for himself and a close friend of his. The friend flew off to a bunch of dodgy countries on an OE and came back to emails being blocked by Outlook/Windows Live/MSN/hotmail whatever the hell they are calling themselves now.
I've tried using this form through Outlook.com. They respond very quickly, often with a one liner telling me there shouldn't be any problems and then a slightly longer email telling me everything should be working fine and that they are not blocking anything. The very first time I contacted them they said something was being blocked and that they had put a 48 hour exception on the block and that it would come in to effect within 48 hours...etc which was looking up! Then back to saying nothing was being blocked. ServInt is telling me I need to contact Outlook and Outlook are telling me everything is fine. Here are the bounce-back emails that we are receiving:

SMTP error from remote mail server after MAIL FROM:<********@gmail.com> SIZE=6207:
host mx2.hotmail.com [**.53.**.553]: 550 SC-001 (COL004-MC6F37) Unfortunately, messages from **.131.**.71 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.
If this is something someone with more experience will need more information about, I can PM the full details.
Has anyone ever dealt with this kind of issue? it says that there was an SMTP error from the remote mail server from my friends side, but goes on to say that part of the service providers network is on a blocklist? I've checked block lists for spam...etc..And the particular IP address and domain I entered came up clean. I've run out of ideas. Help much appreciated!
