    [SOLVED] connect to: [IP]

    Where is this information coming from ? And is it possible that the IP is set only once ? The reason why I am asking is that I've changed the IP address, but the old one is still showing.

    Good strategy against spam from the big players (Amazonses/Google/Outlook) ?

    Hi there, do you have a strategy how to identify spam messages from big companies like Amazonses, Google or MS (Outlook). Every now and then spam mails will slip through Proxmox and I'm not sure how to configure this properly. DNSBL queries will not work as their IPs are probably white listed...

    What improvements can be made for spam detection?

    If you want to improve the DNSBL detection it's worth comparing the various providers, e.g. here For my spam messages DRONEBL and UCEPROTECT seem to work best. You might also want to give different weights for the DNSBL queries, like so: dnsbl-1.uceprotect.net*4; dnsbl-2.uceprotect.net*4...

    DNSBL - How does it work

    Heya, I'm trying understand how DNSBL queries work so that I can improve the configuration and get better results. Let's say I have multiple DNSBL sites (20 sites). Will they all be queried in parallel or only a limited number ? If it's a limited number, will only the first be queried or will...

    Wiki: DNS server

    thanks for the reply. So, disabling dnsmasq or changing its listening port (away from 53) doesn't have any impact on PMG ?

    Wiki: DNS server

    Is this guide still valid for v8.x ? https://pmg.proxmox.com/wiki/index.php/DNS_server_on_Proxmox_Mail_Gateway dnsmasq is utilizing port 53. Would it be better to configure dnsmasq instead of unbound ? What implications would arise by disabling dnsmasq and using unbound ?

    Zen Spamhaus et URIBL too many queries and RCVD_IN_DNSWL_HI

    I have this issue, too. I'm quite sure this was working fine before upgrading to v.8. I had set up the DNS server as per these instructions: https://pmg.proxmox.com/wiki/index.php/DNS_server_on_Proxmox_Mail_Gateway But this guide might need to be updated for v.8.x

    [SOLVED] Limited DNSBL setting

    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...

    Iptables configuration

    So, nobody's configuring their Iptables ?

    Iptables configuration

    thanks again and no worries. Yes, I've tested it and it really does slow it down. After a few hundred entries it takes ages to add a new entry. I'm planning to use Iptables for country blocking and I'm afraid this will just not be feasible with ufw. Which is a pitty, because ufw is pretty...
