Microsoft hat mein Netz für SMTP geblockt. Ich bin ihrem Wunsch nach Nicht-Kommunikation nun nachgekommen.

Die [censored] vom Ausblick wollen keine Mails mehr von einem meiner Mailserver annehmen:

<User.Name@live.de>: host eur.olc.protection.outlook.com[104.47.124.33] said: 550
    5.7.1 Unfortunately, messages from [193.26.120.251] werenmuensterland.de't sent. Please
    contact your Internet service provider since part of their network is on
    our block list (S3150). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.
    [HK2APC01FT115.eop-APC01.prod.protection.outlook.com] (in reply to MAIL
    FROM command)

Nunja, was die können, kann ich auch:

mx.uu.org gave this error:
<mail-oln040092071058.outbound.protection.outlook.com[40.92.71.58]>: Client host rejected: Unfortunately, messages from this IP address are rejected. Please contact your Internet service provider since part of their network is on our block list.

»S3150« scheint ein beliebtesFeature‹ zu sein; wie auch immer, mein Netz, meine Regeln, und wer mich blockt, den blocke ich ebenso. Dankenswerterweise veröffentlicht Ausblick ja die zum Mailversand genutzten IP-Bereiche, so mußte ich nicht das gesamte Microsoft-AS blockieren.

Das ganze ist insofern pikant, als daß Microsoft es selbst nicht so mit Spamverfolgung hat:

Wenn die gefühlten zwei Hektoliter Ausblick-Header-Müll nichts nützen, warum schickt Kleinweich jene überhaupt mit bzw. warum entsorgen “wir” deren X-Header-Müll nicht konsequent?

Anyway: Da Kleinweich/Heißmail/Ausblick einerseits die Spammer unter den eigenen Kunden nicht bekämpfen will, sie andere Mailserver aber kurzprozessig und kommentarlos blacklisten, gibt es offensichtlich keine gemeinsame Linie hier. »Good Netizenship« jedenfalls sieht anders aus.

Schade. Und »cut«.
