    Hello,
    Since some time mail from my server is blocked as it looks like SPAM I think. I am not sure though. A customer gets this mails back.
    Which makes me think it is something what blocks the mails from my server. I am sure there is no spammer on my server, I know all my customers personally.

    Any helpfull thoughts?
    Best regards,
    Rob
