I sent an email to someone at Hewlett-Packard. The Gmail I sent met with delivery failure: "PERM_FAILURE: SMPT Error (state 10): 554 Sender address rejected. This gmail[dot]com mail didn't really arrive via a gmail[dot]com mail server." So then I sent the message via yahoo email client, met with failure, but of different type: "[....] does not like recipient. Remote host said: 550. Recipient address rejected: user unknown in virtual alias table." So my Gmail address and server is bogus, and so is the HP message recipient? This does not seem like sender blocking. What gives?
