PHP: http://gdotmail.com/ Basically what it does is it adds dots to your gmail address to produce multiple variations of your gmail email address. For example, if your gmail address is [email protected], the script will generate every variation of your gmail by adding dots. [email protected] will produce: my.gmail.com m.y.gmail.com my.g.m.ail.com etc.., you get the point. Whenever you email to my.g.m.ail.com or m.y.gmail.com or my.gmail.com, you will receive it on your main gmail account, which is [email protected]. This is very useful when you want to register to multiple web 2.0 accounts but access all of those emails to only 1 gmail account.(works w/ POP too!) For example you register at Twitter with the email address my.gmail.com, and another account with m.y.g.m.a.il.com, you will receive both confirmation links of those 2 accounts when you login at gmail using your main account, [email protected]. To determine the total number of possible vartions of your gmail accounts: 2 ^ (number of characters - 1) so for [email protected] (3 letters): 2 ^ (3-1) = 4 and for [email protected] (12 characters): 2 ^ (12-1) = 2,048 and for firstname.lastname@example.org (13 characters): 2 ^ (13-1) = 4,096 and for [email protected] (30 characters max):(ps: my script doesnt allow that much yet, haha) 2 ^ (30-1) = 536,870,912 Try it for yourself! PS: Script can only handle 15 characters max(thats 16384 emails) at the moment.
