Auto-mode-alist, issue with regexp

[Saptarshi]

Hello,
I would like to open all files whose name starts with
"mail.google.com" in org-mode.
I tried,
1) -->  (add-to-list 'auto-mode-alist '("^mail\\.google\\.com" . org-
mode))

and this doesn't work. Thinking something wrong with my regexp, i
tried to open all files whose name starts with "mail" in org mode,
2) -->  (add-to-list 'auto-mode-alist '("^mail" . org-mode))

which also didn't work.

How do I get (1) to work?

Thank you in advance
Saptarshi
