Currently we encounter difficulties submitting mail from SEPPmail Cloud CH instance to Incamail servers, as Incamail defers some mail with the following message:
host gw2.incamail.com[194.41.147.14] said: 451 4.7.1 Certificate EKU validation failed, please retry later (in reply to end of DATA command)
Delivery of such mail is being retried, and mail remains in our queues for up to 24 hours.
We have tried to contact Incamail and are awaiting their response.
