You can either raise the score for being in the RBL above SA's threshold. Or you can out and out block servers in the RBL from your MTA. You probably want to be carefull with the latter technique since is transfers onus of the work of delivering the mail into the wrong hands. I just spent 3 hours diagnosing a problem for a client on Friday. It turns out that people weren't able to deliver email to him and for the past 6 months he's believed that there was some intermittent problem with his ISP's mailserver. The actual problem is that his ISP is using an overzealous RBL. I found out about this because my delivery server was listed in his RBL due to some mistake that happened in 1999 before my ISP got the IP address. The practical upshot for my client was that until he could find someone who could both see and diagnose the problem he just wasn't receiving mail and thus he was loosing business. Nota Bene for all users of RBLs. -- __o "All I was doing was trying to get home from work." _`\<,_ -Rosa Parks ___(*)/_(*)___________________________________________________________ Christopher Sean Hilton pgp key: D0957A2D/f5 30 0a e1 55 76 9b 1f 47 0b 07 e9 75 0e 14
