Verizon blocking mail - have no idea what they are looking for

Asked by drewster999 in Simple Mail Transfer Protocol (SMTP), Email Software, Exchange Email Server

Tags: Mail being blocked

Basic issue is one of our customers cannot receive mail from us.  We are using Exchange with an smtp server in our DMZ.  I attempted a direct telnet connection and the following results
220-mr4.ash.ops.us.uu.net ESMTP cf-uu-alterdial-$Revision: 1.4 $; Wed, 19 Dec 20

It looks like the error message is being truncated.  Verizon will not help as we are not customer and the customer is not getting very far with them.  Does anyone know if there is something they are looking for that we might not have set correctly.  We don't have this issue with any other customer.Start Free Trial
