Este erro acontece devido ao servidor de origem ter conectado ao MX do Google usando IPv6. Se não há configuração de reverso para o IPv6 que estiver usando, a mensagem acima será mostrada.

Este erro é mais comum em servidores Exchange e pode ser resolvido primeiramente desabilitando o IPv6 da placa de rede do HUB.


Feito isto, execute o comando abaixo, caso retorne status "default" significa que o "6to4" está habilitado.
C:\>netsh interface ipv6 6to4 show state
6to4 Service State        : default
Undo on Service Stop     : default


Para desabilitar execute o comando:

c:\>netsh interface ipv6 6to4 set state disabled

C:\>netsh interface ipv6 6to4 show state
6to4 Service State      : disabled
Undo on Service Stop   : default

  1. Research 3D printing businesses in your area to look at their services, worth factors, and what sells best. For occasion, maybe the native market is lacking a 3D prototype printing enterprise. Advancing applied sciences can make present 3D printers obsolete, creating a need for printing businesses to frequently upgrade their gear. 3D printing is inherently sustainable, but Aectual goes even additional, utilizing one hundred pc recycled waste plastics or bioplastic made from plant oils as an alternative of latest synthetic plastics. They’re also working towards a one hundred pc round production system, whereby they take again a product after use, shred the material and reuse it precision machining to print new merchandise.
