Yes. The last version do spf check and need therefore more mandatory parameter to work (which postfix will transmit, but you didn't) Sorry i didn't explain that. helo_name=google.com sender=bla@firebaseapp.com client_address=8.8.8.8 client_name=mail.google.com < new line > spf-policy...

This is normal in the default setup. The default settings are generally very conservative, so you may need to adjust some of your scores under "Spam Detector" -> "Custom Scores" (don’t forget to click Apply). You can search for filters in the Tracking Center and look for ones that identify only...

Version 3.0: Evaluation of SPF python3-spf, enhanced checks and autoblocklist of bad senders This script will do an awesome filterjob: - filters very early (before DATA) with very little CPU power - high filter-rate - more or less no false positive Installation identically to first post...

I have some similar solutions to this. This rule is designed to detect potential domain spoofing by comparing the visible From header with the SMTP envelope sender (MAIL FROM). It triggers when an email claims to come from one of the organization’s domains (including subdomains) in the From...

I made a description here: https://forum.proxmox.com/threads/installation-advisory.182175/

Dann verwende einfach PCRE Regex Kommentare, um dir deine Notizen zu hinterlegen ;-/ (?#...) [a-z0-9]{1,3}\+bncB[A-Z0-9]{25,}@.*(?# Google Groups)

Man muss nicht nach dem tag suchen, man kann auch nach Absenderadresse filtern. Der Regex, der auf alle Google Groups nachrichten matcht lautet: [a-z0-9]{1,3}\+bncB[A-Z0-9]{25,}@.*

Maybe you deactivated the welcomlist Action Object in Mail Filter?

Spamhaus SA Filter TVD_MIME Filters Beware: SA Filters could add, an email could pop up in multiple SA lists. It is also important to pay attention to the order of the filters. DNSBL and policyguard filter the largest volume. The policyguard autoblocklist [abl] filters a lot and has not...

"blocked using" is the sum of all DNSBL policyguard google groups filter (filtertered google groups only) policyguard google user content: this filter filters HELO strings. i added turbo-smtp, googleusercontent.com and xqueue.com policyguard autoblocklist. this filters sender domains...

i reply to your post on my advisory page

I block (reject) on Score = 7. No mark, no quarantine.

I have also started a new topic for proxmox MG 9.0 https://forum.proxmox.com/threads/installation-advisory.182175/ I also wrote a policy filter for a large amount of google spam here...

I recently answered a few questions here on this topic. It seems that most people are not aware of it, but this is the intended behavior. All emails go through the entire SA filter chain. At the end of this chain, the action object is executed. If a sender is listed under Mail Filter → Who...

I had the same problem on one host yesterday. Thought this was solved over a year ago. modify /etc/network/interfaces with a post-up command helped. iface eno1 inet manual post-up ethtool -K eno1 tso off gso off

I abused the custom script for those actions. Use a custom script: #!/usr/bin/env bash set -euo pipefail # PMG custom check API v1: args: APIVERSION QUEUEFILENAME if [[ $# -ne 2 ]]; then echo "usage: $0 APIVERSION QUEUEFILENAME" >&2 exit 1 fi cp $2 /my_private_copy_of_all_mails/$(date...

Reject unknown senders ("domain not found") or reject unknown client ("cannot find your hostname") is a postfix/postscreen feature and the decision to reject is made long before the SA filter and the Mail Filter -> Who Object -> Welcomelist. You have to put it in a Welcomelist, which is used in...

The Mail Proxy -> Welcomelist is a postfix senderaccess welcomelist. It is a "Trusted Host" feature that prevents getting blocked in postscreen, i.e. for SPF or DNSBL tests. It has nothing to do with the SA checks you did above. For whitelisting SA Checks you need Mail Filter -> Who Object ->...

A big thank you goes to the giants whose shoulders I stood on: christian-b for the rspamd integration: https://forum.proxmox.com/threads/integrate-rspamd-as-custom-script.159110/ heutger zolthar and stoiko ivanov for the GeoIP integration...

Now we have exhausted all third-party plugins. But we can also create our own SA filters. One of the biggest nuisances is "BCC spam". Someone creates a freemail account with a provider that has no outgoing limit and sends spam emails where all recipients are copied in the BCC field. To detect...
