Emails that end up in spam

E-mails
1

Hello,

I am currently experiencing problems with my professional email account. I regularly end up being marked as spam in some people's inboxes, which can cause quite a few issues.

I noticed this problem recently with an @wanadoo.fr address, but I have had the same issue before with other addresses.

I have checked the configuration; everything seems fine according to OVH's recommendations. Using some tools, I saw that the server’s IP is blacklisted on certain lists, but I’m not sure if that is related to this issue.

What can I do in this case?

Thank you in advance.

Best regards,

Hello,

It's an imprecise science where a lot of factors can influence whether something is classified as ham (good) or spam (bad), and the line between the two is sometimes blurry.

Besides the sender's IP reputation (in this case OVH), there are many other parameters that can come into play.

If your domain name is new, that's a deal‑breaker, and nothing can remove this obstacle except patience.

Hola @Unknown_Zoz :waving_hand:

Entiendo que tienes un plan de correo contratado con OVH (MX Plan, Email Pro, Zimbra o similar) y que el problema es que tus correos llegan a la bandeja de spam de algunos destinatarios. Has comprobado que la IP del servidor de OVH está en listas negras. Te explico qué está pasando y qué puedes hacer.

Lo primero que debes saber es que los servidores de correo de OVH tienen protección antispam activa por defecto. Es normal que compartan IP entre varios clientes, y si alguien usa mal su cuenta, esa IP puede acabar en listas negras. No significa que tú hayas hecho nada malo, pero te afecta.

Lo que te recomiendo hacer:

Revisa tu configuración DNS. Para que los correos que envías sean considerados legítimos por los servidores de destino (Gmail, Outlook, Wanadoo, etc.), es imprescindible tener bien configurados los siguientes registros en tu dominio:

SPF: este registro indica qué servidores están autorizados a enviar correo en nombre de tu dominio. Para los planes de correo de OVH, el valor correcto suele ser v=spf1 include:[mx.ovh.com](https://mx.ovh.com/) ~all. Si ya tienes otro SPF, debes editarlo y combinarlo, no crear uno nuevo.

DKIM: este registro firma tus correos digitalmente. En el área de cliente de OVH, dentro de la sección de tu plan de correo (MX Plan o Exchange), busca la pestaña de información general. Verás un apartado DKIM que probablemente esté en rojo. Actívalo con un clic. Si tu dominio no está gestionado en OVH, te darán dos registros CNAME que debes añadir en tu zona DNS.

DMARC: este registro le dice a los servidores qué hacer si falla SPF o DKIM. Crea un registro TXT con nombre _dmarc.tudominio.com y un valor que empiece por v=DMARC1; p=none; rua=mailto:tuemail@tudominio.com. El p=none es seguro para empezar, solo monitoriza sin bloquear nada.

Todos estos cambios pueden tardar entre 4 y 24 horas en propagarse.

Espero que te haya ayudado :slight_smile:

Hello,

Thank you for your help.

My domain is now more than a year old. Maybe time will improve things, let’s hope.

Hello,

Thank you for your response.

Indeed, I have already followed all recommendations. And everything is already correctly entered.

I therefore think there is nothing left to do except adjustments in the DMARC settings or similar.

Thanks again.

Best regards,

Hello @Unknown_Zoz

I regularly end up as a SPAM email in some people's inboxes. And that can cause quite a few problems.

Have you tried creating a support ticket about this? If the categorization is due to Orange, OVHcloud unfortunately won’t be able to do anything :confused:
But if it’s due to OVHcloud’s antispam, support will be able to help you :wink:

Hello,

To test the probability that your email will be perceived as SPAM, there is this service: https://www.mail-tester.com/
You need to send an email to the address provided and then check the score you receive.

There’s also https://www.learndmarc.com/ that checks your DKIM SPF DMARC (with a pretty nice look :slight_smile: ) Unlike Mail Tester there’s no limit (but it’s also less comprehensive because there are no other analyses).

Hello,

Thank you for your help.

Unfortunately I do not have the ability to create an advanced support ticket with my subscription. And it has become very complex to contact someone via their chat.

Kind regards,

Hello,

Indeed, I have already tested this site and I receive a 10/10 rating. So nothing strange on that side.

Thank you for your help.

I just ran the test and everything is green. So no issues on that side.
