Have several clients who use vodafone and are getting their emails returned to sender, saying they are listed on RBLs as per below
JunkMail rejected - mailfilter31.ihug.co.nz [203.109.136.31] is in a RBL
Checked the IP and it is because vodafones/ ihugs mailserver IP they are sending from is blaklisted as shown at

They are phoned vodafone support, but they say it isn't their problem. But it clearly is, as vodafone are responsible to for fixing this problem with their IPs getting blacklisted and getting them removed. Who can my clients contact at vodafone to get this fixed, as the normal support line isn't any help?
