Have suddenly started to find email being bounced by users of Trend Mirco because my static IP address is listed on MAPS DUL database (www.mail-abuse.com). A simple matter to solve just ask TelstraClear to let MAPS know they had it wrong. Not so apparently:
"Trend Micro have listed a large amount of our static IP space in their DUL. We are currently trying to get this removed from the DUL, but due to their conditions this could take some time. In the meantime, I'd suggest you use the paradise.net smtp server as a smarthost. I have checked their BL and this is allowed to deliver mail through the Trend Micro maps service." TestraClear help.
