  3. WARNING: Your ClamAV installation is OUTDATED!

    We have plenty of resources on our servers so this should not be a problem. Also I see no reason why should a message even if it's big be processed for more then a few seconds. If it takes more then 10 seconds there is something wrong with the way the processing works or with some rule or...

  5. Whitelist messages still SA score higher than 0 = makes statistics invalid

    Thanks @Stoiko Ivanov it's all fine we are just forwarding email for that domain to our servers that is why the SPF is fail. They have their own filter we just host email from them and we use pmg to forward their email to our server. I will have to do spamassassin configuration also for AWL...
  6. Whitelist messages still SA score higher than 0 = makes statistics invalid

  7. Whitelist messages still SA score higher than 0 = makes statistics invalid

  9. Whitelist messages still SA score higher than 0 = makes statistics invalid

    Hello, Is it possible to configure the filter to set SA score to 0 if the message is whitelisted? Right now the whitelist messages still score SA higher then 0 even if they are whitelisted and that messes up the statistics. Thanks.

  11. Autoreply from exchange not signed DKIM by proxmox outbound gateway

    @Stoiko Ivanov Thank you very much. This makes sense. I did notice this problem a while ago when testing autoreponse when you send an email to address that does not exist and then you get response back about User unknown. I was thinking that there was something wrong with our configuration but...
  12. Autoreply from exchange not signed DKIM by proxmox outbound gateway

    We send test email from to one of the exchange mailboxes that has autoresponder set. Autoresponder emails should be signed by DKIM but they are not. We get back autoresponder email that is not signed by DKIM. If we try to send email from our domain to gmail our email is DKIM signed...
