There is only one way...convince your ISP to fix their reverse DNS table for your IP, to reflect what you would like it to say. You see, IP addresses are delegated out by another organization...one completely different from those that dole out domain ames. That authority (here in the States, it's ARIN) assigns blocks of IPs to providers, and makes them the authoritative source for the reverse DNS for those IP blocks. Unless your ISP assigns you a block, and then redelegates reverse DNS authority to you, they will remain authoritative for that reverse DNS until they change something to either reflect your info, or to reflect your authority for that space. Since (from what I can gather from your message, it seems that) you only have a couple of IP addresses, it's unlikely that you'll get authority for the block. _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
