I just went through this with this on only on of my almost identically configured, courier servers. I even tied -nodnslookup without success. You might try setting: BLACKLISTS="" in your esmtpd file, restart courier and see how log a telnet to port 25 takes. This probably isn't your problem but if you are as desperate as I was, it is probably worth a try. You can then add the BLACKLISTS back in one by one to see where the problem was. BTW, I had all BLACKLISTS the same on all of my courier servers and only had the problem with one of the roughly 10 ISP's that provide us with internet.
