MAIL_HOST = config['MAIL_HOST'] || '172.17.0.1' MAIL_PORT = config['MAIL_PORT'] || 11_311
+SRV_HTTP_HOST = config['SRV_HTTP_HOST'] || ENV['SRV_HTTP_HOST'] || '172.17.0.1' +SRV_HTTP_PORT = config['SRV_HTTP_PORT'] || ENV['SRV_HTTP_PORT'] || 11_300
Is here 11_300 a clerical error?
older rubocop require 11300 => 11_300 now, we can write as 11300.
Thanks, Weitao
