mailgo not maintained anymore

Problem/Motivation

At https://github.com/manzinello/mailgo the author wrote:

Unfortunately mailgo is not actively maintained anymore. I'm sorry for this but I personally don't have time to maintain it... I hope someone will take over the project.

Proposed resolution

a) Write a notice in the module description, then wait until someone else is taking over maintenance of mailgo
b) Drop this module to "not maintained" as well
c) Maintain mailgo yourself

Remaining tasks

Decide.
