Zwei Kommentare dazu: - Leider hat SRS bei mir das Problem nicht wirklich gelöst. Mein Ziel hat (eine Zeit lang) DMARC Verstöße gegreylistet. Die Anzahl der Greylistings ist durch SRS nicht zurückgegangen. Also ja: SPF Probleme bekommt ihr damit in den Griff. Aber wenn nach DMARC Verstößen...

2026-05-07T10:19:34.783500+02:00 mx pmg-smtp-filter[737784]: 4C31AF69FC4B13AA391: accept mail to <********************> (9B57D4C31BB) (rule: default-accept) This domain is not on your blocklist, or the blocklist action rule is deactivated.

Install the policydaemon from the second post. This should resolve most of your google problems. If you have any questions, ask your questions beneath this forum post. https://forum.proxmox.com/threads/block-google-groups-firebasemail-firebaseapp-googleusercontent-com-in-postfix-before-data.181674/

Introduction Proxmox Mail Gateway has no built-in action to rewrite the mail body — it can block, quarantine or tag mails, but it cannot neutralise links in suspicious messages. This howto shows how to add a custom Defang action module that rewrites http:// and https:// URLs to hxxp:// /...

I like to rewrite the entire body, especially emedded e-mail links so you cannot click them anymore. Edit: Done https://forum.proxmox.com/threads/rewrite-urls-in-mail-bodies-based-on-spamassassin-score.183365/

Das Greylisting Feature des PMG ist leider nicht schön gelöst – rspamd löst es wesentlich besser, weil E-Mails nur dann greylisted werden, wenn sie eine hohe Spamwahrscheinlichkeit haben, während PMG neue Adressen grundsätzlich greylisted. Meine Hoffnung ist ja, dass PMG das auch bald kann...

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 5.0: - Enhances Version with evaluation of SPF python3-spf, enhanced checks and autoblocklist of bad senders - Refactoring with Claude Opus: Optimizing speed and memory usage when first import of logfile - External config file This script will do an awesome filterjob: - filters very...

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...
