Earth to someone Verizon... Earth to verizon... Come in verizon.... come in Verizon... We have an urgent message for you - This is called mail debugging 101. IF upon a successful authentication to your POP servers, the POP servers claim that there is no mail in the inbox while your webmail shows dozen of new unread unopened messages, (you are presented the printout of a telnet session to port 110 of mail.verizon.net)) THEN the claim that it is the "MTU on a customer DSL router" that is causing the problem is wrong especially if the problem manifests itself on a NON-DSL connection. Making these claims for several days after three levels of escalation makes your well-ran operation look incompetent. END IF;
