Our server, pb923js, has a problem sending mail to yahoo! (and probably other mail servers, too). I'm not sure if it's a problem with the Postfix setup or if there is really a problem with our IP address (66.103.254.169).
Here is the response from Yahoo! as recorded by Postfix:
host c.mx.mail.yahoo.com[216.39.53.3] refused to talk to me: 553 Mail from 66.103.254.169 not allowed - 5.7.1 [BL21] Connections not accepted from IP addresses on Spamhaus PBL; see http://postmaster.yahoo.com/550-bl21.html [550]
That link says:
553 5.7.1 [BL21] Connections not accepted from IP addresses on Spamhaus PBL
In our continuing efforts to protect our users from unsolicited email, Yahoo! Mail does not accept SMTP connections from dynamic or residential IP addresses, as determined by the Spamhaus PBL. If you are seeing this error message, please do not retry sending your message using the same IP address. Instead, please contact your ISP for information on which SMTP server you are authorized to use for your outbound email.
If you think that your IP address has been listed in error, you or your email administrator should contact Spamhaus. Once your IP is de-listed by Spamhaus, Yahoo! Mail will automatically unblock your IP within 48 hours.
Why would Yahoo! think that that IP is a "dynamic or residential IP address"?
And yet, when I send mail to my gmail address, it goes through just fine!
Please help us get our mail transfer agent working!
