À la date du dimanche 30 septembre, Outlook (Microsoft) a commencé à bloquer les emails de CLUB1.

relay=msn-com.olc.protection.outlook.com[52.101.41.25]:25, delay=1.8, delays=0.03/0.03/1.5/0.15, dsn=5.7.1, status=bounced (host msn-com.olc.protection.outlook.com[52.101.41.25] said: 550 5.7.1 Unfortunately, messages from [87.91.4.64] weren'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.

Suite au blocage des emails de CLUB1 par Microsoft, j’ai contacté le support le mardi 1 octobre et créé le ticket 7053088134.

Hi,

Thanks you for investigating. Unfortunately, it seems like my problem is not solved yet.

I just tried to send another email from club1.fr domain which is bound to "87.91.4.64" and I still get the same error message:

And the same goes with "hotmail.com"

Thank you for your attention.

On va donc attendre deux jours avant de re-lancer un test d’email vers Microsoft.

J’ai fait un test hier soir et tout a fonctionné !

Le blocage est donc désactivé ! Youhou ! 🎉
