relay

Hallo zusammen, ich habe eine vermutlich doofe Frage. Lässt sich das pmg zwischen Mailserver(n) und Clients setzen, ohne eine Änderung an Mailserver, MX oder Clients? Ich versuche zu beschreiben, wie ich das meine: Ich stelle mir das so vor wie bei einer Firewall, welche zwischen Router und...

I've been contemplating a move back to self-hosting my email services, and I'm considering a setup where I host the mailbox and mail services at home, complemented by a Proxmox mail gateway in the cloud. The idea is to configure the at-home mail server to relay both incoming and outgoing emails...

I am a Linux novice and I am trying to have an internet connection on my Linux machine (Proxmox) by connecting it to a machine containing the internet (create a relay). I connected a Windows machine (where I have an internet connection) to a switch then I connected my Linux machine to the same...

Hello. At first, I apologize for my English. I am supporting the google translator. I have a problem. After setting up the DNS server on the external hosting, I installed PMG. Behind him is the Zimbra server. The current situation is that e-mails reach the PMG but are not forwarded to Zimbra...

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...

I noticed that some spam reports bounce, while others do not: Oct 7 00:05:15 pmg postfix/local[247078]: 8D03AC11D3: to=<j.doe@example.com>, relay=local, delay=0.1, delays=0.07/0/0/0.02, dsn=5.1.1, status=bounced (unknown user: "j.doe") Oct 7 00:05:15 pmg postfix/smtp[247081]: C5DA2C1361...

Hello everyone, sorry if the question has already been asked, I couldn't find anything about it. We are currently using the PMG as a cluster, which filters incoming mail and then forwards it to the actual mail server. Now this infrastructure is to be expanded so that not one mail server is...

Greetings, My postfix SMTP server hosts several virtual domains. Now I am trying to set up postfix to route ALL my email to Proxmox Mail Gateway. Simply putting: relayhost = [pmg-address]:26 in main.cf, almost does the trick: emails sent from a local domain to another local domain are...

Hello, I am running into some issues sending mail and was hoping someone may be able to assist. From what I can tell PMG is sending mail externally exclusively on port 25. I am trying to change it to 587 as my ISP blocks port 25. I have attached an image for your reference. Any assistance would...

I'm not sure if this is a bug (6.0-6) or not. I have tried removing the domain in the Relay, Transports section and then add it back. Just tried updating the host field under Transports, also restarted the server. All resulted the same. Emails being routed to the old destination. To break...

Hi I'm trying something with PMG. What I want to accomplish, is that I can sent mails from different hosts in different public networks on the internet via PMG acting as a SMTP relay. The problem is, that these hosts on the internet are in networks with dynamic public IP's. So I can't at these...

Hi, I do have 2 nodes (Cluster) of Proxmox Mail Gateway and also two relays after them (mx1 and mx2) where the mails get finally dispatched. However, I see I can only set one relay for all mails (currently only mx1). I expected to have the ability to set another one as a backup ? Is there a...
