Hi all I hope someone can help me, I have already spent many hours testing and still can't solve this problem My situation looks like this: I am in the hosting business. I use Enhance Control Panel and have the ability to set up smarthost there, so I built a server with Proxmox Mail Gateway...

Hello :) I have PMG (version 8.1.4 up to date) as a front-end server and a Debian Postfix / Dovecot server (Debian 12 up to date) for mail storage. PMG is used to filter incoming and outgoing mail for spam and viruses. I wanted to add the DKIM signature on Proxmox, I created the selector...

Hello! I recently have got several complains about spam incoming. Analyzing these mails i have found that they are lacking DKIM signature at all and in PMG logs i couldn't see evaluation of this. Log excerpt for mail that have DMARC policy to none, fail SPF with permerror Received-SPF...

Hallo, ich betreibe ein Mailgateway in der Version 8.1.2 für die Filterung des eingehenden E-Mail Verkehrs. Seit der Umstellung auf die neue Version ist mir aufgefallen, dass die DKIM Überprüfung der eingehenden E-Mails sehr häufig "DKIM_INVALID(0.1)" angibt und deshalb auch häufig der Eintrag...

I'm looking into enabling DKIM on my PMG and am wondering what I am supposed to add to the Selector windows when creating the selector. As currently the selector list is blank (see image). Can someone please point me in the right direction? Regards, Aaron

Hi all, I'm wondering if anyone has had any luck whitelisting trusted domains conditional on having an aligned and passing DKIM signature for in the message? The goal is to only skip filtering for messages from that trusted domain that are authenticated. This way it's a whitelist that is not...

Hello Proxmox-Forum, we do have a storage error. We are running a 2-node cluster of the latest mail gateway version in HA mode. One of the nodes started to make trouble delivering mail to external domains (Microsoft-based and others). The error is reproducible. The error message on the node1 is...

Hi, we receive spoofed phishing emails that appear to be coming from our own domain. In order to filter or quarantine those spoofed emails I activated DKIM signatures for our own emails. Now that all "legitimate" e-mails from our domain are digitally signed via DKIM I was hoping I could filter...

Guten Tag Bekommen im DNS, die im PMG unter 'Configuration: Mail Proxy > Relay Domains' angegeben Domaenen, alle den gleichen DKIM-Record, so wie er im PMG unter 'Configuration: Mail Proxy > DKIM > View DNS Record' steht? Liebe Gruesse!

In the current PMG 8.0.7 version postfix internal mails (bounce & notify) will not be DKIM signed - even if the source domain is part of the signing domains. If the bounce sender domain have a strict DKIM / DMARC alignment, some providers are rejecting these important mails. e.G. Incoming mail...

Hello now that we have gotten DKIM signing to work im sitting here thinking what if worst case senario came to pass.. all devices gets encrypted. handing out the TXT record that the users need to enter into there dns servers what if it changes so you have to start from scratch. this got me...

Hallo zusammen, ich habe momentan das Proxmox Mail Gateway in der Version 7.3-6 im Einsatz. Zudem habe ich opendkim und opendmarc installiert und an Postfix angeschlossen. Soweit funktioniert auch alles. Jedoch habe ich im opendmarc Daemon eingestellt, dass die DMARC-Policy ausgewertet werden...

Hallo zusammen, besteht die Möglichkeit E-Mails abzulehnen wenn der SPF verletzt wird. Bspw. wenn die Domain einen Hardfail eingetragen hat? Ich würde gerne E-Mails nur bei einem hardfail nicht bei einem softfail ablehnen. Habe ich im Standard eine Möglichkeit dazu? Die gleiche Frage auch auf...

I'm trying to configure PMG with unbound as local DNS, as explained here. And it seems to work because my firewall logs shows the PMG server is connecting with multiple IP's on port 53 every time I get an incoming email. But I'm also seeing a lot of false positives with this hit...

I have setup DKIM so that mails from our internal network that are sent over PMG get a signature. Now I wonder what to do with our external servers, e.g. JIRA or Gitlab. Those currently send mails via a smarthost but could be switched to using the local Postfix on each server. One option...

Hello, we've got 2 mailgateways in production and we are happy with them. We recently noticed that DKIM is not working if we add a disclaimer through the mail filter actions. If we switch off the disclaimer, we get a valid/ok message for DKIM. If we enable disclaimer we get the following...
