Verizon is a major telco, ISP provider in my area. I've tried telnet'ing from my box and I get connected for about 5 seconds then it drops my connectiom, I get a message that the connection to host was lost.
How I was able to figure out they were blocking my domain was by having a friend from outside my company try to send a basic helo command with the from address a yahoo account and another from my domain account. The yahoo command completed successfully but my e-mail was blocked, I forget the exact error. They are blocking me, it's just a matter of getting someone on the phone who can help me. > I think that depends on the response code that your server receives from > the target SMTP server.
