    i have created a forward to someones mailaccount but i keep receiving those errormessages.

    • hostname && hostname -f are the same
    • dig domain.com SPF is the correct ip
    • reverse DNS record at Hetzner is hostname.domain.com
    • postfix config has hostname.domain.com in it, nothing else
    • dig domain.com MX gives me domain.com

    did i forget anything?

    thanks in advance, giftsnake

    The error message said that you tried to use a gmx.net address as sender email address (and not as recipient). This will not work, you have to use a sender address of one of your domains as you most likely dont own the domain gmx.net.

    mh, is that the only function of forward-addresses?
    thought i could forward to any mailaccount at any domain!

    what i did:
    create a new forward testforward at domain.com
    typed the destination email(s) (most of them accepted my forwarded mail from gmx)

    is this destination email limited to my own domain?

    and of course i can send emails to this forward from any domain, even if i dont owe them

    You can forward to any address at any account, but you seem to have used a wrong sender address in the email that you forwarded and thats why gmx refuses it.

    when i send an email with my gmx directly to that adress, everything works fine.

    same settings/config/username in the mail program!
