Description of my issue

Hello, I’ve discover today that my server is blacklisted from some emails provider, and I don’t have any idea why…

First thing, I don’t use the email with yunohost, so I don’t send mail from yunohost and I don’t receive emails also. This is why in the logs bellow you can see that yunohost is not properly configured, I don’t care about this point:

    id: mail

        details: 
          - You should first try to unblock outgoing port 25 in your internet router interface or your hosting provider interface. (Some hosting provider may require you to send them a support ticket for this).
          - Some providers won't let you unblock outgoing port 25 because they don't care about Net Neutrality.
 - Some of them provide the alternative of using a mail server relay though it implies that the relay will be able to spy on your email traffic.
- A privacy-friendly alternative is to use a VPN *with a dedicated public IP* to bypass this kind of limits. See https://yunohost.org/#/vpn_advantage
- You can also consider switching to a more net neutrality-friendly provider
        status: ERROR
        summary: The SMTP mail server cannot send emails to other servers because outgoing port 25 is blocked in IPv4.
      1: 
        details: 
          - Current reverse DNS: xx-xx-xx-xx.subs.proxad.net
Expected value: xxx.nohost.me
          - You should first try to configure the reverse DNS with xxx.nohost.me in your internet router interface or your hosting provider interface. (Some hosting provider may require you to send them a support ticket for this).
          - Some providers won't let you configure your reverse DNS (or their feature might be broken...). If you are experiencing issues because of this, consider the following solutions:
 - Some ISP provide the alternative of using a mail server relay though it implies that the relay will be able to spy on your email traffic.
- A privacy-friendly alternative is to use a VPN *with a dedicated public IP* to bypass this kind of limits. See https://yunohost.org/#/vpn_advantage
- Or it's possible to switch to a different provider
        status: ERROR
        summary: The reverse DNS is not correctly configured in IPv4. Some emails may fail to get delivered or may get flagged as spam.

          - You should first try to configure the reverse DNS with xxx.nohost.me in your internet router interface or your hosting provider interface. (Some hosting provider may require you to send them a support ticket for this).
          - Some providers won't let you configure your reverse DNS (or their feature might be broken...). If your reverse DNS is correctly configured for IPv4, you can try disabling the use of IPv6 when sending emails by running 'yunohost settings set smtp.allow_ipv6 -v off'. Note: this last solution means that you won't be able to send or receive emails from the few IPv6-only servers out there.
        status: ERROR
        summary: No reverse DNS is defined in IPv6. Some emails may fail to get delivered or may get flagged as spam.

But, I’m worried about the blacklisting because I don’t understand why.

Furthermore, my principal fear: is it possible that my instance is infected and included in a botnet? How can I check that everything is OK on my server?


Bonjour, j’ai découvert aujourd’hui que mon serveur est blacklisté par certains fournisseurs d’emails.
Je n’utilise pase yunohost pour les emails, donc je n’en reçoit ni n’en envoie jamais. C’est pourquoi mon instance n’est pas complètement configurée sur ce point (voir 1ère section de logs).

En revanche, je ne comprends pas la raison du blackistage et surtout j’ai peur que mon serveur soit compromis. Fait-il parti d’un réseau de spam? comment vérifier son intégrité?

J’ai cherché sur le forum mais rien trouvé…
Merci Ă  vous!!

Salut Ă  toi,
Rassure-toi, Spamhaus bloque par défaut toutes les adresses IP considérées comme étant affectées à un usage résidentiel. Il faut leur faire expréssément la demande si tu souhaites faire retirer ton adresse IP de leur blacklist.

Si tu n’utilises pas le mail tu peux juster cliquer “Ignorer” pour ignorer ce problème.

OK merci mais comment se fait-il que ce soit apparu récemment?

@Aleks oui j’ai vu mais je voulais être sûr de ne pas avoir un “vrai” problème avant de l’ignorer!
