Question

Hello. As an Orange subscriber, I've been receiving a flood of identical emails from the Mail Delivery System: Undelivered Mail Returned to Sender, all with the same body message generated automatically by the server mwinf5d35.orange.fr
I've checked that my Orange email password hasn't been compromised.
What can I do to block these unwanted messages?
Thank you for your responses.
Best regards.

Hello,
these are emails that you send and that cannot be delivered to the recipient either because their inbox is full or there is another problem with their messaging.

Hello @Chris67550_0100,

Hmmm, there's a strong suspicion that your account has been hacked and the hacker has added dozens or hundreds of email addresses to your contacts, some of which are invalid. They are using your account to spam/scam these addresses, which is why you are getting returns for invalid addresses (if that’s indeed what is indicated at the end of the "undelivered" messages that you didn't share with us)!

Otherwise, please show us the complete error message because the cause of the non-delivery is in the last words at the end.

See this tutorial:

Thank you.
Here is a copy of the "undelivered" mail. They are now adjacent to authentic emails (same window)
We are sorry to inform you that your message could not
be delivered to one or more of its recipients.
This is an automatic message generated by the server mwinf5d07.orange.fr.
Please do not reply to it.

This is the mail system at host mwinf5d07.orange.fr.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients.

<contactnoripply@gmail.com>: delivery to host gmail.com[108.177.97.27] timed out

Hello @Chris67550_0100,  Timed out  Here are the two important words that indicate the cause of non-delivery. This means that the recipient server did not respond in time.  This address is probably fake. Check if you don’t have mail forwarding to this address in your settings and follow all the recommended corrective actions in this tutorial.

Hello and thank you for this response. Understanding English perfectly -having taught it for 42 years :) - "timed out" was not an issue for me and I had also noted contactnoripply instead of noreply, which suggests that it might be a hacker who doesn't master English with this bogus address contactnoripply@gmail.com. I have of course never written to this fake address and I don’t see how it could be in my preferences. So thank you for the response, but where is "this tutorial"?
Oh, by the way, I checked online: my email address has not been compromised ("no leaks").

Bien sûr que oui ! Merci quand même.

Chris67550_0100 · Answer

Wow, what a crazy tutorial. It takes weeks to do everything!

SerBal22 · Answer

Thanks for the "Wow".  No, no, not that much. It only took me a day, plus a few improvements afterward.

Chris67550_0100 · Answer

For now, I no longer have any spam messages. Wait and see. I will try to do it in less than a day ???? !

SerBal22 · Answer

Have you found a redirect in your preferences and have you deleted it?

Chris67550_0100 · Answer

Good evening! I couldn't find any Preferences in the tabs of my email settings, and there was no forwarding either!
I spoke with an Orange advisor online, who confirmed that someone had indeed accessed my email, and he simply had me change my password (which I had already done yesterday) and wrote to me: don't worry, everything is fine.
Hmm, is that really true? The near future will tell me.
Have a good weekend, and thanks again... and maybe see you later.
Christian

Chris67550_0100 · Answer

Well, I found in the Orange webmail settings (which I hardly use!) the mail forwarding tab, which was already set to the "do not forward" option.
And of course, as I feared, despite my password change and the assurances from the Orange advisor, I still received five "undelivered mail returned to sender" messages tonight without the slightest mention of the so-called message returned to the "sender," with an attached file file.dat that I can't open. Demonic, isn't it?

SerBal22 · Answer

Hello @Chris67550_0100,

The Orange "advisors" unfortunately still have a lot to learn. Among other things, they need to understand that changing a password does not prevent someone from sending an email to that account!!!

These messages may have been sent late or gotten stuck on one of the servers. A complete header analysis with timestamps would indicate that.

Are these messages all identical? Same fake Gmail address? Same "Timed out" reason?

Chris67550_0100 · Answer

Hello and thank you again for your interest. Without being an "internet wizard" of your calibre, I was skeptical about the effectiveness of a simple password change. I've read a lot of exchanges on the web regarding this hacking issue, and many do say that after a few days or weeks the spam emails stop following a password change. But maybe it's just a coincidence. The system here doesn’t allow me to add an attachment, so I can't send you a sample of these spams, but yes, it’s always the exact same text, with the same characters without accents and the same rather comical noreply in the fake sender address.
Last night I received "only" four spams. Maybe there is hope...
Come on, let's enjoy the sunshine!
Have a nice Sunday
Christian
