Software utilities

On a recent Gmail official blog post, two interesting hidden features were exposed. The first one is that when you have a Gmail address, let’s say myaddress@gmail.com, you can add a plus sign at the end of the user name (technically, the local part) to get additional addresses (in this way, you get unlimited addresses!). This can be useful in many situations. The first one can be to filter particular messages, let’s say, you use myaddress+bank@… for your bank account, and star or filter it. Since this can be exploited by spammers, I suggest you to use more sophisticated names, not a simple +bank, to certify the authenticity of an e-mail. You could also use this feature to track your e-mail, for example, you give it to someone with a +id123 and when you receive an e-mail to that address you know that that person gave it away without your permission.

Another hidden Gmail feature is that it does not recognizes dots in the username, so my.address and myaddress are the same for Google. Dunno how one could use this, any ides?
