I find the way PMG handles Postfix Gateway features very good, and I would like to combine these features with an external mail filtering service, such as Kaspersky Security for Mail Server. This allows integration with Postfix via the Milter API Is this integration possible? Where can I get...

Hi ! Just adding a new node to the cluster and am seeing this in the mail.log pmgpolicy[22026]: WARNING: file /etc/pmg/pmg.conf line 25 (section 'spam') - unable to parse value of 'extract_text': unexpected property 'extract_text'#012 Checked the /etc/pmg/pmg.conf file on the node and master...

Hi, My root user has an email address configured, i changed it, but i still see postfix trying to connect to the old email domain. Why does this keep happening? Thank you!

Hi all. I've installed postfwd to add some needed functionality (such as limiting senders to X emails per hour and queueing the rest, etc.) however, postfix cannot connect to the postfwd service. I know its not technically a PMG issue, but, does anyone have any ideas on this one? I've install...

Hi there, I believe it is possible to configure Postfix's DNSBL settings to have entries like this: zen.spamhaus.org=127.0.0.[10;11]*8 zen.spamhaus.org=127.0.0.[4..7]*6 zen.spamhaus.org=127.0.0.3*4 zen.spamhaus.org=127.0.0.2*3 b.barracudacentral.org=127.0.0.2*7...

Hello, Is it possible for postfix to recognize regex inside a virtual alias file? I wrote some regex in /etc/postfix/virtual, but it does not seem to be read. Here is one example of my regex: This should catch any addresses such as contact+help-desk@example.com and send it to...

Has the vulnerability SMTP-Smuggling (CVE-2023-51764) already been mitigated in the current PMG standard setup? https://media.ccc.de/v/37c3-11782-smtp_smuggling_spoofing_e-mails_worldwide#t=1836 https://www.postfix.org/smtp-smuggling.html

The box (PVE1) was installed on top of Debian and recently upgraded to 8.1. Tried (unsuccessfully) setting up postfix after upgrading before learning about the new SMTP notifications system, which was set up successfully and backup jobs send emails as expected. However, cron jobs are not sending...

Is there a way to restore postfix's main.cf to its contents after installation? I accidentally overwrote it's contents.

Hi there, A quick question about Postfix configuration: how do you guys manage this effectively within your cluster? Do you have a dedicated container that does SMTP relay and "collect" emails from the rest of the cluster? Do you do it by node? What about CTs and VMs? I'm running a 9x nodes...

Hello everyone, I am trying to setup postfix to send me system emails via gmail exchange. I've had this setup without issue on proxmox 7. I am now running proxmox 8 fully updated. I set everything up. Unfortunateyl the following two commands (using proper email addresses) do not work. ```...

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...

I have been testing PMG for a while now and I have to say I'm impressed. I like how simple it is to use. There is one thing that it's missing though. You can have finer grained control (than domain level) by putting me@example.com in transport_maps by using virtual_alias_maps. # transport...

Hi, For a few weeks we have stopped receiving the emails that scheduled backup tasks send when they finish their execution. We only receive emails if we execute them manually. When they automatically execute the emails, they remain in the 'deferred' state and are not sent. root@pve01:/var/log#...

Hi, I'm having a problem with the outgoing emails, when it fails it keeps trying to send the deferred emails an excessive amount of times. That is a problem because some times our emails could be considered as spam. What can I do to set a limit to the retries attempts? I'm using Proxmox Mail...

Hallo kann mir das wer bitte weiterhelfen, ich habe die main.cf.in nach /etc/pmg/templates kopiert und um folgenden Eintrag am Ende erweitert: smtp_header_checks = pcre:/etc/pmg/smtp_header_checks apt install postfix-pcre habe ich auch installiert Die Datei /etc/pmg/smtp_header_checks nun...

Maybe I'm not using the appropriate search terms, but I can't seem to find where I can change the email template for notifications from Proxmox. I've configured postfix and SMTP is functioning perfectly, but I am not a fan of the way emails look; email name: vzdump backup tool (not ideal)...

Piggy-backing off this thread: https://forum.proxmox.com/threads/pvemailforward-loses-emails-if-mail-server-is-not-available.108893/post-495825 How should I set up the dependencies for a systemd service to ensure mail delivery during startup & shutdown of the system? From the thread linked...

Bei meiner Proxmox Neuinstallation werden E-Mail Benachrichtigungen an zwei zusätzliche E-Mail Adressen versendet. set@proxmox.local und escape@proxmox.local. Ich finde einfach nicht heraus wie ich das unterbinden kann. Postfix und Fail2Ban habe ich bei meiner alten Installation exakt gleich...

I'm wondering if any body else is having issues. I have stopped receiving notifications from PVE. Either through Outlook or Gmail accounts. Could this have to do with their emails becoming more secure? Or perhaps this is an internal issue? I would appreciate help. I think the latest email I...
