PRODUCTIVITY: Use TWO gmail accounts to protect an ISP email account

Many people advocate using a gmail account to protect against spam.

In my normal blundering way, I’m using two gmails to protect my ISP account from spam, and giving me a fully authenticated email address using gmail’s plus sign feature.

So let me see if I can explain how to duplicate the Yahoo AddressGuard. You can create and manage disposable email addresses to defend your primary address against spam. In Yahoo’s offering, they assign you a base name, unrelated to your real email name. Then Yahoo allows you to create suffixes that are just a string of characters. A real email address is created by base name, a minus sign, a suffix, and @yahoo.com. The suffix gets appended to the base separated by a a minus sign. (Great minds think … differently!) So if your real name is ABCDEF and your base name is ZXCVBN, then you can create, for example, ZXCVBN-EBAY. Then the address ZXCVBN-EBAY@yahoo.com will forward to ABCDEF@yahoo.com and you can even send from ZXCVBN-EBAY! Should your ZXCVBN-EBAY get spammed, then you can turn it off! They are easy to create, but there is no reporting or database with it. AND, it ain’t free!!!

So I sought to recreate that capability with GMail.

To refresh your memory, GMAIL (to their credit) has innovated by adding the capability to allow a plus sign in the email address. So if your gmail email address is abcdef @ gmail dot com, then you can put anything you want after a plus sign. So if email comes addressed as abcdef + fedcba @ gmail dot com will get delivered to your email account and you can test on that stuff after the plus sign.

Web sites may choke on the plus sign. (Gripe at them and don’t use their site till they fix it!)

I wanted to keep the base name concept. And, you want to control & database those suffixes. So here’s my concept.

I have an ISP account I want to protect called NORMAL@isp.com. So I created a “front door” account called FRONT@gmail.com and a “back door” account called WEIRD@gmail.com.

To test it all out I set it up so that FRONT forwards to WEIRD and WEIRD forwards to NORMAL. When it all works, I break that forwarding.

So far no big deal, just moving a lot of messages around. Except that FRONT does get vacuumed for spam by Google.

Now lets start using suffixes.

I created a table of suffixes and record where I use it. I then create a filter in the FRONT gmail that forwards FRONT+suffix to WEIRD+suffix. Then over on WEIRD, I create a filter that forwards WEIRD+suffix to NORMAL.

NOW:

* NORMAL only gets authentic pre-approved email.

* WEIRD is the protected hidden yahoo BASENAME equivalent.

* FRONT messages without a suffix get stopped there.

* FRONT and WEIRD get Google’s vacuuming for SPAM.

* If WEIRD is guessed by an alpha spammer, doesn’t move to NORMAL without a filter.

* Should any suffix be compromised, it can be stopped quickly by deleting the equivalent WEIRD filter.

* A web site, or intruder, who drops the suffix, to spam you, doesn’t reach NORMAL.

I think you need WEIRD, the second hidden BASENAME equivalent, so that you can change FRONT from time to time as needed. You could also have multiple “front doors” (i.e., FRONT1; FRONT2; etc.) feeding one WEIRD.

This a free solution equivalent to Yahoo’s address guard. It’s a great spam preventive.

For example, I now give each use of my gmail address a unique unguessable random code. (You expected different from a fellow who uses long strange email addresses?) Any email that arrives without a “plus code” is suspected of being spam. Should I get spam, I can pinpoint where the breakdown occurred.

Your comments, please?

  1. How do you cloak your ISP email NORMAL address when you are replying to emails that have been forwarded to your ISP mailbox. Everybody talks about how to protect from inbound SPAM but I have not seen anything on what you can do to cloak outgoing messages.

    surprised you boys get any mail at all – what i like to do is add random charcters to my address and get pre – approval to send -if someone doesnt call me on my mobile to get that pre – approval code the moment they send the email it doesnt get through….. clever hey!!!

    p.s.

    havent had an email in five years… live in hope.

    Sounds like a lot of work compared to spamgourmet.com or similar sites.
    Plus with spamgourmet, you can limit the number of emails sent, and stop guessing out right by adding a secret word that you can change periodically.
    ie: if I signup as ‘userx’
    and want to provide a email to contact me, but limit the number of times one can contact me to 5 I would just input an address such as blog.5.userx@spamgourmet.com in the email field (rather than having to log in and configure an account)

    if spammers figured out this generation technique, then I could start appending a secret watch word that periodically changes. all currently active addresses would remain active, but no new addresses could be activated with out matching the current secret word. Further the word can be just a word part, ie:
    sercet.blog.5.userx@spamgourmet.com
    and blogsecret.5.userx@spamgourmet.com would both work.

    More over, there is a new feature that allows one to substitute letters (based on their position in the alphabet) in place of the number so:
    blog.e.userx@spamgourmet
    allows 5 emails as before.

    Finally, any address is limited to a max of 20 so after the letter ‘t’ all the letters = 20. If you want more than 20 messages for a particular address, you can log into spamgourmet and “refill” the number of messages left “up to 20” or you can add the email address to your “trusted sender” list. in which case you will continue to receive email from them until you turn them off.

    Kooky but cool gmail spamguard idea

    I came across a gripe that topix forums don’t support plus signs in their email addrs in my daily topix vanity scan… John Reinke has come up with a way of forwarding gmail accounts to each other with disposable suffixes…
