Anyone know what e-mail authentication and DomainKeys/DKIM are all about and how to use them?

I read a blurb from Yahoo about better protection from phishing e-mails and they said eBay and PayPal were now using them in their program.

Is there any way WE can filter e-mails in this way or does it have to be done by an ISP?

Steve,

do you have a url that I can look at?

You are talking about encrypted e-mail. The sender and receiver each have a private key and public key. The sender sends a message signed with their public key which the recipient would use to authenticate the message against the private key at the certificate authority. Signing and encrypting messages ensures that a message that is intercepted can not be read by others and it ensures that the message is actually from the sender and not a haxor. Go to http://na.pgpstore.com/product.aspx?sku=... to purchase your own public and private keys. Please note that the key is valid for one e-mail address only and if you change e-mail addresses you must get a new key.

Does that mean that we need a special key from eBay to receive their e-mails?

Well this is fantastic, that yahoo is doing this because then I don't have to block them anymore.

Paypal, and Ebay has never been an issue for me or my clients. It's those "free" email accounts that seem to be the biggest problem.

Free always seems to come at a cost.

Looks like all you have to do Steve is sign up for a free Yahoo! mail account and point your eBay and Paypal accounts to the new e-mail address.

I would like to know why even though I have my spam blocker set to automatically delete what it considers spam(yahoo), why am I still receiving 30/40 spam emails in my inbox daily and I opened one and it wasn't even my email, it was a variation of it. So how did it get there and how do I stop it?

Good question. I hope someone can answer that.

Spammers have found ways to trick spam filters into thinking that a message is valid. For example for a while spammers were using an image of their message as the message. That method no longer works like it used to because mail server admins developed methods to combat this type of spam. Now spammers are using intentionally misspelled words and misleading subject lines to trick spam filters. Although the spam filter does not recognize the misspelled words, humans can still comprehend the message. How you stop the spam from reaching your inbox depends on many factors like whether or not you use webmail or a mail reading program like Outlook or Thunderbird. If you use a webmail service like Yahoo Mail or Hotmail then you are limited to the protections put in place by the server admins. If you use a webmail service you can still setup POP3 download of your messages to the program of your choice which will allow you to use your own spam filters. I use a server side spam filter along with two client side spam filters and I still get the occasional spam message in my inbox.

Nathan,

One of the questions that confuses me the most is how an e-mail comes to me when it is not my e-mail address in the To: bar.

View the full message header and you will find your e-mail address.
