Tonight, I received a spam mail sent to A.BCD.HelloWorld@gmail.com and intrigued how it could arrive in the in box of ABCD.HelloWorld@Gmail.com my proper GMail account.
BTW, the above e-mail addresses are fictitious containing only structural information, like the presence or absence of a . to illustrate how GMail mishandling e-mail addresses.
So I did some experiments. I sent an e-mail from my hotmail account to A.BCD.HelloWorld@gmail.com and lo and behold, it arrived in ABCD.HelloWorld@gmail.com.
I did that with several other GMail accounts some with no '.' in the address and I could add as many '.' as I like and they were obediently sent to the address without '.'.
I took my other GMail account like this OneBrownFox@gmail.com and sent e-mail to O.n.e.B.r.o.w.n.F.firstname.lastname@example.org and without failing it ended up in OneBrownFox@gmail.com.
In other words, GMail tries to guess e-mail addresses and that kind of dangerous practices can increase the SPAM mail you receive. In E-Mail format, the '.' is significant. That is OneBrownFox@gmail.com and One.BrownFox@gmail.com are two distinct e-mail addresses with distinct inboxes. But in the eyes of GMail, they are not.
So far GMail is the only e-mail service that seems to mishandle e-mail address in this manner.
