Using Craigslist

[COLOR=black][FONT=Arial]I’m experiencing this weird problem as I use craigslist to find a job. A lot of the postings don’t have their own email addresses and the craigslist provided ones for those entries don’t work. You know, where it says: “Reply To: [email protected]”? Are these email addresses supposed to work? Has anyone else experienced this too?[/FONT][/COLOR]

Ok I figured it out (I think haha). This is the message I’m getting:

Client host rejected: rDNS / DNS validation failed. Please set up matching DNS and rDNS records.

So I need to configure my server’s DNS settings (I think)? Does anyone know how to do that and if that actually is what I’m supossed to do?

Thanks for the help guys - much appreciated
