the compass-support mailing list is restricted to members of the COMPASS team, hence the reason for not accepting your subscription. It is a "hotline" where you can ask questions to our team.
There is another list called email@example.com, where we circulate news on COMPASS, and it is open to everyone. Perhaps it is of interest.
