How do I keep hotmail from sending spam from my closed email acct.

How can I get hotmail to stop sending spam to all of my contacts even though I have closed the acct.?
I searched the older questions but they seemed gmail specific. I closed my hotmail acount and people are still getting spam (or something else) from it. I have not had any luck from customer support. I'd appreciate the help.

your account got hacked. spammers have all the contacts in your address book. they're sending from hacked computers (not from hotmail). they're using a fake "from" address, unfortunately, your address.
there's nothing you can do. the accounts gathered by the spammers will continue to receive spam until the end of time, especially if the list gets sold to other spammers. they won't always be spoofing you as the sender, but there is nothing to stop them from doing it. Probably best, since you deleted the account, to have all your contacts set up anything from the old address in a blacklist, filter it directly to the spam folder.

One thing you could have tried was deleting all of your contacts from Hotmail

You can't. Most modern mail readers have some kind of filter, so you just have the people from your contact list automatically send email from the bad address directly to the trash can. It will always be spam from now on.

A lot more common that actually using your account to send spam email, spammers are just faking the address their sending from. So it seems the email is sent from your address, but it's actually not. (Yes, that is pretty easy to achieve). That happens a lot without your account being hacked.
If that is the case, there's nothing you can do but ask every of the recipients to use decent spam filters. Those usually filter such faked addresses pretty well.

Basically, email was designed by scientists in the 70's for sending messages to each other. There's no security or verification built into it. The 'sent' field can be anything you want it to be. You can even change it in most email clients.
Why on earth would you put the wrong address in the sent field? They thought. You'd never get the replies!
That commercial penis enlargement pills spammers would see that as a feature never occurred to them.
The term for this particular problem - a spammer using your address as the sender, so you get all the bounces and complains - is known as a 'joe job' in the business.
There are a couple of systems by which companies can specify which servers are allowed to send email for their domain (SPF and DKIM) but that only helps the receiver mail server spot the message may be faked. Implementation is spotty at best, so it's not that reliable.
In your particular case, there's very little you can do. Given your account is now closed, the best thing your friends and family can do is put that address in their blacklist, so it always go to trash. Since that mail was never coming from hotmail in the first place, just being faked to look like it was, there's nothing they can do either.
Welcome to the war between server admins and spammers, where 95-99% of all email worldwide is spam/virus, mostly sent from botnets spewing out millions an hour per pc.

How do spammers fake the sending address?
The computer equivalent of whiteout, basically.

Response by poster: If I hadn't closed the hotmail acct. would there be another remedy. Additionally, if it is my computer itself that was hacked, how long until it messes with my other email accts?

Well, if you computer itself is hacked then it is probably already too late for your other email accts. Anything you type on your computer (login/passwords) can be read by the hacker.

No. It's like somebody walking around in the streets claiming they are you and working for your previous employer. There's no connection between you and this guy, just like there's no connection between your previous email account and the spammer.

On the client's end, they could look into some basic mail firewall/antispam technolgies. Even though the email "appears" to be coming from you, the MIME header of that email will attest to something different entirely. Take for example this e-mail header:
---
You can immediately see some inconsistencies, such as the message-ID not having a fully qualified domain name at the end (example of a spoofed Message-ID). More importantly however, you can see that the From: email address does not come anywhere close to the Received: header's originating server. Here's another one for good measure pulled from my yahoo spam folder:

---
This one is particularly easy to pick apart, you can see right away that the From: and Reply-to: do not match, essentially redirecting all replies to a possibly hijacked account. You can also see that the Received: header and Message-ID: are from Taiwan's specialized branch of the FBI of course ;)

aniola: "How do spammers fake the sending address?"
The same way you'd fake a return address when sending postal mail: you just put something else in that blank spot.
There are enough people sending email with @gmail addresses through their Comcast cable mailservers that server admins can't just require that the email address match the sending server's domain. Too much legitimate email would get refused and bounced back to the sender.

Response by poster: I guess I'm going to send an email to my entire contact list telling them to dismiss or report as spam anything coming from that address and get a good anti-virus program. All the technical stuff is great to learn, thanks.

When you do please add their email addresses to the BCC field, not the TO field. Not following this is part of the reason an individual gets more spam or their email address is used as a from-address.
Still, I wouldn't do nothing at all. They will see it's spam, they should know to have anti-virus anyway.
