I have a question relating to my Gmail account although I will use a fake email address for the purpose of this question.

My Google email account is myaccountname@example.com but then today I received an email, which is addressed to my.account.name@example.com. (note the periods .)

Is this a bug of Gmail or is this intended behaviour?

I've checked the mail headers and I am sure that there is no cc or bcc to myaccountname@example.com, but yet I received them.

  • You can check the headers to see who is BCC? – Dave Rook Mar 25 '13 at 10:56
  • @DaveRook if it is really bcc to me I can see it. Just tested... (or I could actually be wrong...) – Alvin Wong Mar 25 '13 at 10:59
  • AlvinWong, I made an update to the question, if you don't like it, roll it back :) I don't know you can see the BCC but if you've found a way... – Dave Rook Mar 25 '13 at 11:00
  • Having periods in the username makes no difference to gmail. So myaccount@domainname.com and m.y.a.c.c.o.u.n.t@domainname.com are the same – pratnala Mar 25 '13 at 11:14

This was a decision made in the early days of Gmail. You can also create additional addresses with the + symbol that will arrive in your inbox. This page goes into detail, as does this Gmail support article
