Because while it is a valid Python regexp
<http://docs.python.org/library/re.html>, it doesn't say what you mean.

The correct way to say what I think you mean by that is

  ^[^@]*@facebookmail.com

I.e. [^@] matches anything which is not '@'; [!@] matches just '!' or
'@'.

However, I would use

  ^.*[@.]facebookmail\.com$

to match any address in the facebookmail.com domain or a sub-domain or

  ^.*@facebookmail\.com$

to match addresses in only the facebookmail.com domain.
