[Compass-ci] Re: [PATCH v6 compass-ci 1/7] container/send-internet-mail: mail-post.rb

TO ALL: 请把cryptic过程 包装为一个底层函数，起一个描述性的函数名。 必要的话加comment.

+mail_server = %x(/sbin/ip route | awk '/default/ {print $3}').chomp

Please encode the above %x() into a function. The function name should reflect what it does. Thanks, Fengguang
