@Stoiko Ivanov I understand your point but I do not agree with it. I was expecting this answer that is why I simplified the configuration so now I have just one ruleset for all domains. But again even with this setup I cannot do what I want to do. Why would you not want to optimize and minimize...

Hello, From server IP 1.2.3.4 I just want to receive and pass email to server 2.3.4.5 without any processing. Is it possible to completely disable filtering including SA score for just one sender server (IP address). I have created Rule with top priority that accepts mail from this sender but...

Been noticing this in the logs for some senders, receivers. Any idea how it works and if it's good or bad? Example from logs: Nov 21 15:54:35 server postfix/smtpd[8412]: connect from mail-yw1-f171.google.com[209.85.128.171] Nov 21 15:54:35 server postfix/smtpd[8412]: Anonymous TLS connection...

So I am struggling to make this optimal it seems like every way I try to configure this it just does not work the way I want it. I don't want to configure yet another mail gateway just for this it's too painful to manage just one pmg. I understand there are limitations with pmg...

As far as I understand if you use MX then PMG will use MX records priority for delivery. If the record with lower priority is offline PMG will try to deliver email to the second record with higher priority. This is how it usually works. https://en.wikipedia.org/wiki/MX_record#Load_distribution...

On the email logs you will usually see what rule was triggered for that email. Can you provide the anonymized logs for that blocked email? How are your priority rules set on your filter can you share? Is it possible that you have rules that have the same names? make sure they are named...

@clsaad not everything is listed in changelog. Upgrade to latest PMG and test if it works then if does not come back to this thread. You will have to upgrade sooner then later don't run unsupported versions and ask for help. It's not helpful to anyone. If you are running latest version you are...

I would vote against making such rules. It's very easy to get a very high number of false positives if you have many different rules with Message as Field so be very careful if you decide to make such rules... I would always say no I will not even start making such rules because this is a never...

You can try this: Everything else I think you have configured correctly at least on proxmox. You need to make sure your server is port forwarded correctly and your DNS records are OK too (like MX, SPF, PTR records to just name a few).

There is an active thread on https://old.reddit.com/r/sysadmin/comments/yzm5hc/shout_out_to_proxmox_ve_devs_best_hypervisor_imo/ about proxmox ve and personally I am interested in drawbacks and limitations vs other enterprise virtualization products. As we are starting to adopt more proxmox in...

@keeka can you actually confirm that sender domain has SPF records configured correctly? For SPF check I usually use https://app.dmarcanalyzer.com/dns/spf?customerid=0 it's a great tool.

I was worried about this too but after enabling it I only had 3 people notify me that they can't get the email and it was related to this change. We have average 20k mail flow per day. I added exception and warned the providers that have their mail servers or dns records configured incorrectly...

The most important thing you left out. Show us the Mail Filter menu where you see the rules https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#chapter_mailfilter Depending on the rules you have the mail will be blocked or quarantined. Your spam score is high enough on the message because...

I have the same problem I have tried to enable Configuration - Mail Proxy - Options - Reject Unknown Clients Configuration - Mail Proxy - Options - Reject Unknown Senders Configuration - Mail Proxy - Options - SMTP HELO checks Configuration - Mail Proxy - Options - Use SPF Configuration - Mail...

@Stoiko Ivanov I can confirm that 7.1-10 fixes this problem. This is much better X-SPAM-LEVEL: Spam detection results: 0 DKIM_SIGNED 0.1 Message has a DKIM or DK signature, not necessarily valid DKIM_VALID -0.25 Message has at least one valid DKIM or DK...

Send you the information via email. Let me know if you need anything else. I see this error on all messages. Usually I open them via outlook so the message is in the .msg format. This was all working fine on version the 7.1-7

I am running version 7.1-9 because of this https://forum.proxmox.com/threads/mail-flow-broken-on-7-1-8-patch-on-specific-case.117796/#post-510604 I am seeing that in the messages that are passing the filter the X-SPAM-LEVEL is in the wrong format Example: X-SPAM-LEVEL: Spam detection results...

Here is the overview of what I did in the end. The reason is the limitation from pmg as noted by Stoiko https://forum.proxmox.com/threads/how-to-disable-clamav-daily-cvd-main-cvd-bytecode-cvd-databases.117813/#post-510260 I had to spin up an additional proxmox mail gateway just to be able to do...

Some of your rules in the Mail Filter - Who Object - Regular Expression are invalid. Check https://forum.proxmox.com/threads/proxmos-email-gatwey-who-objects-blacklist-not-working.105496/#post-454376 https://forum.proxmox.com/threads/matches-null-string-many-times-is-regex.351/#post-380850 I...

I can confirm that the patch fixes the issue. I don't see the errors anymore and messages are now parsing to tracking center. Thank you very much for such a quick resolution! You are amazing!
