Email: Germany DE SMTP blocked by iCloud

At the present time email sent to @icloud.com addresses via our DE SMTP server is being either deferred or bounced. We're working with Apple to resolve the issue and will update this post when more information is available.

In the meantime, DE mail customers can work around the issue by using our alternate DE SMTP server in their email client settings. The alternate server is: smtp2.de.opalstack.com

  • The block was cleared as of 14:22 UTC today. Mail sent to iCloud email addresses via our DE SMTP are no longer bouncing.

  • Apple informed us that our SMTP is caught up in a block of a larger IP address range operated by our network provider. Our provider is working with Apple to resolve the issue.

    If you are affected by this you can configure your mail client to use smtp2.de.opalstack.com as its SMTP server as a temporary workaround.
