Membership disabled due to excessive bounces

Hi Guix,

Today is the second time I receive a membership deletion email from the
mailing list (first one was on the 31st of October).

It starts with:

> Your membership in the mailing list Guix-devel has been disabled due
> to excessive bounces The last bounce received from you was dated
> 11-Nov-2018.  You will not get any more messages from this list until
> you re-enable your membership.  You will receive 3 more reminders like
> this before your membership in the list is deleted.

I've re-enabled my membership both times.

My email is hosted by https://gandi.net (I use their email hosting
service).  I send emails with Emacs' mu4e if that matters.

Does anyone know why this happens?  I've never had this issue before
with any other mailing list (most of them also hosted by Mailman).
