Re: 209.68.1.140 (209.68.1.0 /24) blocked by bellsouth.net for SMTP

That would be the one. They have a /18 that contains that /24 that I mentioned. Bellsouth.net has finally
issued for me NOC TICKET 577106. They had no previous ticket on this trouble for Pair.net. I hope
pair.net was glad to find me through Steve Schustack of fort-lauderdale-marine-directory.com. Probably
not and I'm doing this consultation for free ;-) I think I just might be the only one that got results. Maybe
I can get a supporting engineer position at Pair.com. Or maybe a support contract.

* In addition, Pair networks says the following:In our experiences, most blocks occur from users forwarding their domain email to an outside address such as Bellsouth. Since a customer forwards all mail, legitimate and spam, the ISP will see the spam deliveries and block the offending IP, our server. In most cases, the ISP is willing to work with us and the customers to limit the amount of mail being forwarded. In this case, Bellsouth refuses to correspond with us. Should you have any additional questions please let us know. Thank you,Jaime P.pair Networks* I had not heard that kind of indication before. I hope if someone isforwarding domain email to bellsouth.net that they will stop...---

I wonder if anyone with Bellsouth.net can tell me why this ip or /24

209.68.1.140 (209.68.1.0 /24)

would be blocked from sending SMTP to bellsouth.net customers.

That's a large (and quite good) webhost called pair.com, which also
hosts the Pittsburgh IX (pitx.net)

Blocking is fine - happens.  Postmaster and other role accounts not
replying at all to email that they're sent is just not a good thing to
do.
