Looks like a connectivity issue between Sprint and UUNet/Alternet. Here's a couple of traces, one from London, one from Virginia. Please excuse the excessive layout.

Hi people, we are having issues sending mail to Ameritrade.com.

It looks like their firewall is dropping the smtp connection to smtp.ameritrade.com (199.200.9.140) from us.

I can connect to it from our US server and they claim that they have lots of NZ customers with no issues.

So I think they are blocking the 210 block of addresses (we show up as 210.48.112) because we share that with Korea. (This is not a mail server block, we don't get a connection to the mail server, so it must be the firewall in front)

Could get some of you to try to telnet to smtp.ameritrade.com on port 25 and let me know the result and the block it's coming from?

I need some concrete evidence.

Thanks.

jfp.
