My email gets rejected

Using /e/OS murenacloud
1

Hi,

I started using my @murena.io email address recently and noticed that two emails didn’t arrive, one of which bounced with a message stating that part of the Murena network is on a blocklist.

I’m aware that Murena has had issues with spam by customers in the past which might explain this.

My question is if someone is working on this and if there is some timeline for when this will be fixed.

I need to be able to trust that email that I send will arrive (or at least bounce).

Best regards,

Andres

I think that specifics are appropriate in an issue like this, but required if anyone was to try to ameliorate.

It just occurred to me that using a vpn when sending mail from my phone might be the problem, as I use the mail client on my phone.
In which case: apologies, I could have thought of that sooner. I forgot to exempt the mail client from ip hiding.

I sent a test message to my hotmail account, this is the reply I received:

My son has been having the same problem for at least two weeks and maybe up to a month: Whenever he sends Murena email messages to anyone on outlook.com email, the messages bounce with the same type of error message @Andres reports from outlook.com. This has also been reported elsewhere: Can’t send email to Microsoft addresses - /e/OS Devices / Murena - /e/OS community, Not able to send mails to Hotmail accounts - Using /e/OS / Troubleshooting - /e/OS community, and Email rejected by outlook.com - Using /e/OS / Applications - /e/OS community.

Furthermore, my son has the same issue from his T2e and from his computer (both from webmail and an email client), regardless of what type of internet connection he is using. Yesterday, I followed the instruction in the bounce message: “Please contact your Internet service provider since part of their network is on our blocklist (S3150).” Our ISP checked everything on their end and noticed no blocks. They suggested that the problem is on the email sending server and that we should contact the email provider. Any updates on this problem?

This happened to me about a year ago, and from what I can tell it was an issue with a relay server in Germany. This got sorted last year so can’'t understand what is taking so long. I can’t email my eldest. HelpDesk were trying to resolve this issue, but clearly it is still an issue. Whilst this is ongoing I am using Proton Mail to family members who have Microsoft mail accounts (outlook.com and hotmail.com)

I’ve been having troubles sending emails to hotmail accounts for some weeks. I can send emails to accounts at gmail or other providers, but sending mails to hotmail give the following error:

Is there a solution to this? As several of my contacts stick to hotmail it’s kind of showstopper for switching over to Murena / e/os.

Issue is being followed up with Microsoft. We have not received a response from MS as yet.

I too have same issue when I send messages to hotmail accounts.

I experience the same issues, resulting with the same replies of the mail system at host mail3.ecloud.global, when sending emails at [@outlook.com>].
Thank you Manoj for following this issue, we are all awaiting for a solution.

Same issue here. I am using Thunderbird on a laptop.

Happy to provide my bounce messages if helpful.

We are awaiting a clear response from Microsoft. What we have got so far are automated response mentioning that our IPs are not blocked. That being said the email delivery is still failing. Our team has sent these failure messages to the Microsoft support team and awaiting further investigation and response from their side.
I will update on the progress.
