I'd probably just write something simple like:

h = s.attributes
h['mail'].gsub!('@',' (at) ') if h['mail']

If you really want to iterate, then

h = s.attributes
h.each { |k,v| h[k] = v.gsub('@',' (at) ') if k=='mail' && v }

And if you want to write it as a one-liner, look at inject or merge. If
you know there's always a mail attribute, then:

s.attributes.merge( 'mail' => s.attributes['mail'].gsub('@',' (at) '
).to_json
