How can I get Verizon to block all outgoing messages on my email?

[key9989]

My email was apparently hacked, it is the main account that I have used for the past seven years and all of my bill notifications and important things come to this address.  I have changed the password repeatedly, run several scans on my main computer, laptop, kindle fire, and cell phone (every device I access the email on) using Norton and Norton Power Eraser on the computers.  Nothing showing up.  

I chatted with support just now asking them to block all outgoing email and they said it isn't possible and I find that impossible to believe.  I am seeing all kinds of messages here saying that people are being blocked but I can't add an email address to that list?  I need to keep it active for inbound email for a month or so just to make sure that I haven't missed any bill notices or other important stuff.  Any ideas?

Thanks!

Pretty hard to do without shutting down the account.

Assuming you have properlly changed your password, and checked your PC and other devices for viruses/trojatns/etc. Then the person using your email is probably NOT even using Verizon.  \

Unfortunately the basic SMTP protocol is totally different then most people think.  Who you say you are is not a protected value and you can say you are anyone, yes verizon's servers when initially accepting input do check, but that is about it.  And the displayed sender and addresses in the smtp protocol do not have to match any text in the mail. that you see.

Typical smtp conversation

EHLO

a bunch of auth commands

MAIL and whoever i claim to be

RCPT

aaaa@someisp.net

bbbb@anotherisp.net

...

DATA

this is what most people is the email and its headers, but can really be anything.

FROM:  SOMEone

TO:  you and everyone else they can think of
