Hi Brajesh,
Re: the comment on the blog entry - http://buddydev.com/plugins/buddypress-premium-plugins/plugin-bp-auto-activate-auto-login-redirect-to-profile-automatically-activate-your-new-user-signuplog-them-in-and-redirect-to-their-buddypress-profile-on-signup/comment-page-1/#comment-506
The BP version we're using is BP 1.1.2, not BP 1.2.
I just applied the main differences between BP 1.1.2 and 1.1.3 for the activation process:
http://trac.buddypress.org/browser/tags/1.1.3/bp-core/bp-core-activation.php
http://trac.buddypress.org/browser/tags/1.1.3/bp-core/deprecated/bp-core-deprecated.php
And the activation email was still being sent.
Is there something I'm overlooking?

Also on the plugin release page, it says the version number is v1.1 (January 2), but the downloaded version is v1.0 (December 1).
Does v1.1 fix the problem?
