tl;dr fixed. If you use those domains you may have missed some posts this weekend.

On the weekend, subscribers to the Mailing-list with email addresses with TLD GMX, and at web.de (both belonging to the same provider) had their subscriptions disabled.

Investigations found that the provider implemented stricter DKIM checking. DKIM is one of the anti spam authentication measures.

The server hosting the Mailing-list was blocked from sending/receiving emails to those domains.
The Mailing-list sees that as bounces, and the addresses as unreachable, and hence disables the subscription.

A specific DKIM key was added to the OpenSCAD domain, which should fix this.

The affected email addresses have been re-enabled.

So you will hopefully receive this notification.

There were not many posts, if you wish to see any you may have missed, check the list Web interface at:

This is getting repetitive.

The relevant addresses have been enabled again.

This is also another test message due to the lack of normal posts.

---===============================

Anyone with an email address with GMX.* or WEB.DE, please read my earlier post below.

Well, it was not quite fixed.
We have added more definitions and hopefully that fixes it this time.

Third time lucky, touch wood.
The subscriptions were disabled again, it seems like it may be due to a backlog of rejected emails.

They have been re-enabled.

Torsten received the recent posts, so we are assuming it is now fixed, but will check tomorrow.
