Is your feature request related to a problem? Please describe.

At my $DAYJOB we have [email protected] as email addresses. The default regex for finding mail links don't include dots before the @ sign, so only the [email protected] part gets included in the link.

Describe the solution you'd like

Change the default regexes to include dots before the at sign. Perhaps

\b\w+(\.\w+)*@[\w-]+(\.[\w-]+)+\b

Describe alternatives you've considered

I can of course change this myself in my local config but I figure that it would be good to change the default option as well.

Regexes are an insufficient tool to correctly parse all possible email addresses but this is a pretty common format for email addresses and it would make sense to have them included.

Looking at the regex, perhaps hyphens before the dot could be included as well?
