Domains in email addresses

[simonwheatley]

Should we ensure that we don't replace the domains within email addresses. So example.com/something gets replaced to example.local/something, but bri@example.com is left untouched?

Similar to #1, I'd like to avoid implying anything about the input. I think we can form searches such that email addresses don't match. i.e. ://example.com
