You are sending directly from your desktop. Yeah... that's bad for 
Verizon, m'kay?

Verizon does CBV (CallBack Verification). This means that when you 
connect to them, they will in return connect right back to you on the 
SMTP service port. If it doesn't get a connection, your transaction 
will be dropped. Most likely, the other verizon.net emails went through 
your MX (ftp.ece, still, right?) and since you're trying to send this 
through the desktop, Verizon is snapping you off in the middle. Send 
the email through ftp and I'll bet it gets through.
