Hotmail/Outlook blocked server's IP, but this server not sent emails yet NEVER

This isn't serious. I bought a new server with a new IP, we not sent never emails yet.

When my client try to send email to Gmail, Yahoo and other companies receive him without problems. But Hotmail/Outlook block the IP and return this message:

Code:
"host hotmail-com.olc.protection.outlook.com [x.x.x.x]
SMTP error from remote mail server after pipelined MAIL FROM:email@email.com SIZE=1797:
550 5.7.1 Unfortunately, messages from [x.x.x.x] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3140). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [.eop-EUR01.prod.protection.outlook.com]"
WTF!!!, this is frustrating. How can happens this if we never used this server and have a new IP. I did test with many blacklist tools and the IP is clean.

Hotmail/Outlook need disapear, they are blocking IPs for nothing.

Hetzner.com ? Does Hetzner Company really care about its customers !!

Hello,

I've really strange issue with this careless company called Hetzner,

I've server with them for shared hosting, there was abuse for one site on it and they sent me mail to resolve this abuse in only 1 hour or they will block the service for the main server ip .

I've seen this mail after 2 hours, when all of my clients sites has been stop working , I checked my E-mail and i got this message on junk mail (no problem till now)

Then, I've sent reply to Hetzner abuse department, that i have solved this abused issue and deleted the abuse file from my client hosting site,

They didn't reply me for long hours, and keep blocking my main server ip which makes all my clients sites down !!

After that, i sent message to support, Hetzner support replied me with very strange reply !!

Please note that it's 02:20 CET Saturday morning. So currently there's no one available I regret. Most likely they will be back in office by Monday 08:00 CET.

They want me to wait more than 2 days with server down because they blocked it and went to the weekly vacation !!!

How Hetzner imagine the clients can wait more than 2 days with all sites down ? Could a company that respects its customers block server for 2 days till there employee ends the vacation ?

Do you think that clients can trust you again after making them losing there business ?

What is the regret that your company gives ? Does Hetzner really respect its clients ?

It's very bad experience with Hetzner

More email Deliverability problems WHM/cPanel

Hi,

I received some tickets from clients hosted in the old server that says have a problems when try to send emails.

I did some tests and when send email to some accounts I received this warning:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

info@receiver.com

Reporting-MTA: dns; nameserver.domain.com

Action: failed
Final-Recipient: rfc822;info@receiver.com
Status: 5.0.0
From: info@sender.com
To: info@receiver.com Too I checked "Email Deliverability" in WHM and appear this message:

-DKIM: The system failed to complete validation of nameserver.domain.coms DKIM because of an error: (XID z736ms) DNS query (default._domainkey.nameserver.domain.com/TXT) timeout!
-SPF: This system does not control DNS for the nameserver.domain.com domain and the system did not find any authoritative nameservers for this domain. You can install the suggested SPF record locally. However, this server is not the authoritative nameserver. If you install this record, this change will not be effective. Contact your domain registrar to verify this domains registration.
-PTR: The system failed to complete validation of nameserver.domain.coms PTR because of an error: (XID 958s2v) DNS query (IP.in-addr.arpa/PTR) timeout!

The server where I have the DNS work correctly. Why happens this?. How can I solve him?.

Thank you very much for your suggestions. Have a nice day.

Hetzner.com | Problems With Abuse

Hello friends,
Hetzner, I have several servers on the Company. There are many websites on my servers. One of my customers' website cloudflare was complained and this complaint was forwarded directly to Hetzner.
The content of the mail is exactly as follows.

Hetzner sent me the following e-mail. We analyzed my customer's site in detail, but we realized that Hetzner does not violate any terms of use, someone seems to have complained unnecessarily to my customer's site.

Later I did a research on Hetzner. I saw that there were some people who received this kind of mail. They say that if I do not remove my client's site, they will cut off access to my server's IP address within 24 hours.

Has anyone had such a problem?

TailorMadeServers Review by RIADVICE

Intro:

We ordered our first server from TailorMadeServers in March 2021 for few customers using BigBlueButton for their online conferences. And now we have 39 servers with them. The fully story is below.

Hardwa 10/10
What we like about TailorMadeServers is their unique baremetal servers. Just send a contact e-mail to ask building the server with your required hardware and configuration and almost all the possible configurations are possible if the hardware is available in the market. We first started with a small 1271v3 server then we got a Ryzen 3900XT for our BigBlueButton MP4 SaaS and now we have around 30 servers with dual E5-2620v3 running web-conferences with media streaming.

Pricing: 9/10
The pricing is unbeatable, one of the lowest we could find among the competition.

Support: 9/10

TailorMadeServers provided us with servers in little to no time after the incident of OVH, and with higher CPU capacity!
They helped us set 33 servers in a matter of 4 hours, which means 1 server every 7 minutes.
We have managed with the help of TailorMadeServers, to bring back the BigBlueButton conferencing system to all our customers affected by OVHFIRE in Kuwait, Saudi Arabia and some other countries.
100% of our Bigbluebutton web-conferencing capacity wouldn't be possible after 24 hours from OVH-FIRE without the incredible support and commitment of TailorMadeServers.

Service: 9/10

Recently, one of the BigBlueButton servers at Tailor Made Servers has attained 742 concurrent participants across 15 meetings and we had no post complaints from our customers.
Moreover, below is an example of some of the web conferencing capacity and number of concurrent users within our customers servers at Tailor Made:
- University 1 in Middle East: 77% of web-conferencing capacity. (4000 to 4600 concurrent users)
- University 1 in Middle East Exams & Admission: 100% of web-conferencing capacity. (300-600 concurrent users with high demand on webcams)
- University 2 in Middle East: 100% of web-conferencing capacity. (800-1000 concurrent users)
- University 3 in Middle East (Dental care and pharmacy): 100% of web-conferencing capacity. (1200-1500 concurrent users)
- A call center for medical appointment schedule and tele-consultation: (40 to 50 schedule daily)

Features: 8/10
- On-Demand hardware.
- Remote Reboot
- 100Mbps Ports
- DDoS Protection

Network: 8.5/10
The network is reasonably stable, bandwidth ports are becoming increasingly more generous as time passes!
No major network problems can be mentioned, and while there has been some rare speed drop, the overall experience has been positive.
Furthermore, their DDoS security is excellent. Usually, every single server under the TMS umbrella is protected 24/7.
We would like to see offers with 250Mbps ports.

Outro:

You will receive friendly and personal support at all stages, from pre-sales questions to your server provisioning.
Once you are hosted with TailorMadeServer, you will only wish you had tried TailorMadeServer sooner!

2TB HDD for email server

I wonder, can good 2TB HDD 7200RPM (for example WD Gold or Black) can handle 1 KVM virtual machine (1CPU 3,54GHz, 8GB RAM) with all email server functionality (Postfix, Dovecot, Spamassassin, webmail Roundcube, etc.).

I total this KVM server would handle 400 mailbox'es. Let's assume that each user will use POP3 on computer and IMAP on Phone. About 10% users will use webmail. Also each user will SEND 50 and GET 50 emails per day.
Each year a user will grow mailbox by 1GB, so in total after 3 year the space will be occupied 3year x 1GB x 400users = 1,2TB

So my question will such combination be enough in terms of performance? What do you think about random read/write operation, won't it be slow?
Users quantity is not so much, but I want to plan infrastructure very carefull that I won't need to redone everything when we start the all things live.

This HDD will be on CEPH cluster storage, so we don't talk hear about the local RAID.
I can't afford SSD though.

Good people, could I have your advice?
