Mailserver blocking Vivaldi Mails: "Undelivered Mail Returned to Sender"

Sorry, I could not found a fitting forum thread for my topic.
Since last week I can't send mails from mail.vivaldi.net any more. I got "Undelivered Mail Returned to Sender" from different mail servers like gmx. The reason: "Message rejected as spam by Content Filtering." There was no content in mails and tried with different @vivaldi.net accounts. Seems like @vivaldi.net is banned because of spaming.
Currently @vivaldi.net mail accounts can't be used.
Could someone have more information about this?
The admins checked this: GMX used some filter lists.
As is remember Vivaldi's mail admins have contacted GMX beginning of December to remove the IP from the blocklist.

Seems to work now.
I send two mails from @vivaldi.net to my gmx account one only with text and one with some attachments (a pdf and a xls) both arrived within a minute
OK, good to hear your mail sending works.
