That’s really an issue to consider, I’ve totally removed any spam filter from my postfix config, rather have spams in my spam box than having important emails silently rejected without any information !

Hello, sorry I won’t be of any help unless to tell you that it is NOT just you, and it seems like an important thing to investigate ! This happens to me with various emails simply never showing up.
When I did the command line you suggested it showed : postfix/smtpd[20526]: NOQUEUE: reject: RCPT from unknown[171.22.30.237]: 554 5.7.1 Service unavailable; Client host [171.22.30.237] blocked using [cbl.abuseat.org](http://cbl.abuseat.org); [https://www.spamhaus.org/query/ip/171.22.30.237](https://www.spamhaus.org/query/ip/171.22.30.237); from=[spameri@tiscali.it](mailto:spameri@tiscali.it) to=[spameri@tiscali.it](mailto:spameri@tiscali.it) proto=ESMTP helo=
I know for a fact that just yesterday a personal email and a neocities email never showed up.

Hi @nouckey
Your answer does help actually by letting me know that I’m not the only one.
Thank you for your feedback.
My point here was mainly to raise a concern about it and show how to investigate if you suspect it happened to you.
As I said previously though, I’ve commented out all 3 lines responsible for spam filtering, in `/etc/postfix/main.cf`
```auto
# reject_rbl_client bl.spamcop.net,
# reject_rbl_client cbl.abuseat.org,
# reject_rbl_client zen.spamhaus.org,
```
The result is that I have one spam every 2/3 days, but all the legit emails are back in my mail box.
While waiting for the YNH team to get any interest in this matter, to not have any spam filtering is way better than the default and faulty setting.

Oh I didn’t understand that you actually did it ! Thank you for re-explaining that to me, I sudo nano the sh\*t out of that antispam hihi, hope that will work, that’s exactly what I wanted !

The issue is stated there.
Some documentation about it: [DNSBL Error Code - Open/public resolver - The Spamhaus Project](https://www.spamhaus.org/returnc/pub/) and [Successfully accessing Spamhaus' free blocklists using a public DNS - Spamhaus Technology](https://www.spamhaus.com/resource-center/successfully-accessing-spamhauss-free-block-lists-using-a-public-dns/)
Basically your server uses an open resolver, and SpamHaus does not like that as it can be abused to circumvent their free tier.
In my case, my OVH VPS was automatically configured (in `/etc/resolv.conf` or `/etc/network/interfaces.d/` I think) with their own DNS servers. Removing that and making sure our own `dnsmasq` was used fixed the issue.

YunoHost is configured to use open resolvers for privacy concern. So it seems we have a problem here…
Anyway, for what I’m concern, without spam filtering, everything is fine.

Is this issue tracked somewhere in the Yunohost project? Where could we report the issue? It feels rather serious as I understand it impacts any user with the default configuration.

Had this same issue where all incoming email was being marked as spam, commented out the spam lists for now.
There should be an option to configure whether emails marked spam should be rejected or tagged as such

Hi, what was the solution to fix this? I’m facing this issue now with my bear-host server from [OHV issue with receiving emails](https://forum.yunohost.org/t/after-migration-from-contato-to-ovhcloud-vps-receiving-email-fails/28086/2). Can you redirect me to the right direction.

I have also been facing a similar issue:
– a couple times even emails from friends who I have corresponded with in the past via email have been marked as Spam and moved to the Spam folder without me realizing.
I haven’t yet looked into logs of why they were marked as spam, but this thread has helpful leads, and I will try turning off the spam filter for now.

more than a year later I can say that I’m very happy with this fix commenting out anti-spam filters ! (my issue was the non-delivery period, and not the mail arriving in spam folder)
In a year I’ve had about 60 spam emails, usually caught in the “spam” folder of thunderbird, so that causes very little inconvenience.
And I now actually get better email reception than with professional providers (I’m looking at you infomaniak, but frankly gmail was not better and the source of many headaches for email providers)
(my self-hosted adress is not my main adress, but is linked with my public domain name)

Can anybody on the Yunohost dev team explain why removing these over-aggressive spam filters isn’t the default, or at least an opt-out/in during installation? Receiving a bit more spam can be annoying (although, like others, I’ve faced zero impact to my spam filtering after commenting out the filters due to Thunderbird filtering), but _not_ receiving important mail from legitimate sources can be a show-stopper for using Yunohost as a mail server.
And if there are no plans to change the default, would an opt-in/out install/config option be welcome as a contribution?

And if you deactivate in:
```auto
/usr/share/yunohost/dnsbl_list.yml
```
```auto
- name: Spamhaus ZEN
dns_server: zen.spamhaus.org
website: https://www.spamhaus.org/zen/

What is the situation and recommendation to deal with this? I noticed that enabling the RBL is still the default, and also the use of public resolvers. So it is a matter of being lucky until I will run into this problem?
As for the `/usr/share/yunohost/dnsbl_list.yml` file: is that even used by postfix? It seems unrelated and rather to be the source of the diagnostics check for whether the IP of my server itself is on any blocklists - not about which blocklists the server should ask/use. Correct?
Edit/addition: the current default configuration is also not using “error codes” as recommended here by Spamhaus itself:
[https://docs.spamhaus.com/datasets/docs/source/40-real-world-usage/PublicMirrors/MTAs/020-Postfix.html#configuration](https://docs.spamhaus.com/datasets/docs/source/40-real-world-usage/PublicMirrors/MTAs/020-Postfix.html#configuration)

Hello there,
I had a similar issue (VPS from OVH, sending mail from my server was fine, but receiving always failed)
For me the solution was to modify `/etc/network/interfaces.d/50-cloud-init` (as hinted by @tituspijean) as such, and reboot
```auto
# This file is generated from information provided by the datasource. Changes
# to it will not persist across an instance reboot. To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
auto lo
iface lo inet loopback
# dns-nameservers 213.186.33.99 # this is an OVH IP
auto ens3
iface ens3 inet dhcp
accept_ra 0
mtu 1500
# control-alias ens3
#iface ens3 inet6 static
# address /56
# post-up route add -A inet6 default gw || true
# pre-down route del -A inet6 default gw || true
iface ens3 inet6 static
address
netmask 128
post-up /sbin/ip -6 route add dev ens3
post-up /sbin/ip -6 route add default via dev ens3
pre-down /sbin/ip -6 route del default via dev ens3
pre-down /sbin/ip -6 route del dev ens3
```
Commented lines was the previous configuration,and I redacted the IPv6 addresses. If I understood everything correctly, this:
- remove the custom DNS imposed by OVH
- setup IPv6 properly (disabled by default for OVH VPS): [Setting up IPv6 | Yunohost](https://doc.yunohost.org/admin/troubleshooting/ipv6/#with-a-vps-from-ovh)
I also configured reverse DNS on OVH web interface (for both IPv6 and IPv4)

With Yunohost 12.1.x it is now possible to deactivate spamhaus,cop,abuse checks for incomming mails.
Thanks folks. ❤
