Why start off with the .*?

In a regex it's irrelevant as regexes are always substring matches unless
anchored with ^ or $. /@domain\.com/ matches the same as /.*@domain\.com/ but
uses less memory.

Personally, I'd do acl whitelist domain /domain\.com$/ or /@domain\.com$/. The
difference being the first one will match sub-domains (ie user@...),
but the second will not.
