Does anybody have an idea what the reason is?
I see the same on my site as well - queues are growing. But you also
find in the internet that t-online-customers complain since yesterday
that they have porblems receiving e-mails.
its a RFC 7505 problem here :=)
just not for subdomain, i like to be fair if my custommers want to
complain
not fair that t-online can send to my custommers, but not possible to
reply, feel free to take that battle
