My system has proxmox mail gateway products in front of the mailenable standard.
There is no problem with incoming and outgoing mail controls, but in accounts with redirection to gmail from the e-mail address on mailenable, the proxmox tracking center section (if there is a post that I approved...
Since quite some time we noticing mails from domains were wrong SPF / DKIM configuration is unlikely (Dell.com / gmail.com / microsoft.com ) are failing the DMARC check and logical are taggt as spam.

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...
We have an internal Exchange Server which receives an sends mails through pmg. LDAP is not set up, so its only a gateway.
All is working as expected so far.
We have an DMARC and an SPF entry setup which tells to reject non conform mail senders.
Here comes the problem, were I want to find a...
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...

Hallo Community,
ich bin derzeit dabei meinen Mailserver mit SPF, DKIM und DMARC auszustatten. Die Diskussion ob es nun Sinnvoll ist oder nicht, sei mal dahin gestellt.
Während SPF und DKIM einfach zu implementieren sind, fehlt mir bei der Validierung von DMARC die Kenntnis wo ich den...
Hallo Zusammen,
in einigen DMARC-Reports bin ich darauf gestoßen, dass angeblich DKIM-Checks für Mails meiner Domäne fehlschlagen würden:

</dkim>

Hi,
For the past few weeks, I've been having problems with incoming e-mails from Yahoo.
PMG is putting them into spam, when they are not.
When I open the information about the spam, I see that there is a DMARC_REJECT that adds 10 points to the spam score.
What can I do about this?
Thank you...
In der Dokumentation zur PMG finde ich folgendes:
Proxmox Mail Gateway verifies DKIM Signatures for inbound mail in the Spam Filter by default.
Leider werden bei Inbound E-Mails weder ein "Authentication-Results" Header, noch weitere Informationen zur DMARC Richtlinie o.ä. gesetzt.
Ist das ggf...
Hi there. Here's a how-to for adding authenticated SMTP (smtps and submission against AD, or LDAP), DKIM (both verifier for inbound and signer for outbound) and DMARC support to PMG
