Welcome to blackholes.tepucom.nl - RBLDNS since 1997

The only point of contact is Tepucom Abuse Dept. at abuse@tepucom.nl
Note: if you have "never received any abuse complaints", your abuse mailbox is probably behind a spam filter which filters abuse complaints: bad idea, really bad idea. Stop doing it.
