I got a spam from mout-xforward.gmx.net and was surprised that sending IP was widely blacklisted including by Spamhaus. Is "mout-xforward" a separate service that has a big outgoing spam problem?



mout-xforward.gmx.net is used, if the user has a forwarding enabled and GMX has tagged the mail as SPAM. If the mail was not tagged as SPAM, the mail will be forwarded through their "normal" MX servers.

Same for web.de, as they belong to United Internet AG too.
In this case mout-xforward.web.de is used for SPAM.
