I tried to send out the announcement email for Mesos - I used my apache
email, but got the response "sender not allowed here"

Does anyone have any idea?

Subject: Apache Mesos is now retired
Announcing that the Apache Mesos committers have voted to retire the
project due to inactivity. Mesos was a cluster manager that provides
efficient resource isolation and sharing across distributed
applications.

Retiring a project is not as simple as turning everything off, as
existing users need to both know that the project is retiring and
retain access to the necessary information for their own development
efforts.

You can read more about Mesos's retirement at:

   https://attic.apache.org/projects/mesos.html

The project's resources will continue to be available in a read-only
state - website, mailing lists, wikis, git, downloads and bug tracker
with no change in url.

Providing process and solutions to make it clear when an Apache
project has reached its end of life is the role of the Apache Attic,
and you can read more about that at:

   https://attic.apache.org/

Thanks,

Niall
on behalf of the Apache Attic and the now retired Mesos project
