See post 15. Thank you for the help. :)

I just cleared the verification database again and rebooted the whole appliance and it still is quarantining emails vs bouncing non-existent emails. Here are two snippets. First is for addresses that don't exist and it's spam. Feb 19 10:11:07 smtp postfix/smtpd[1126]: connect from...

Hrm, Ok, I did clear the verification database last night. I didn't restart. It is working, if I send it from a valid email address, it will reject non-existent email addresses, but only to valid emails. It the incoming email is spam, it's sending it to the spam quarantine. Let me restart the...

I did have one more question. Is there a way to set the precedence to verify the sender before verifying it's spam? What I see happening is that Proxmox quarantines email for accounts that are not on the Exchange server, rather than verifying the recipient exists first, then checking for spam...

Ok, so I got it resolved. Turns out the Exchange server never had the Spam filtering installed. These directions resolved the issue. Thank you for pointing me in the right direction. :)

That makes sense, I'll look through and see what I find. I'll post my results back later. Thank you! :)

Here is the log, it pushes it through to Exchange even though it doesn't exist on the backend. I end up getting an NDR to the sender as well. Feb 15 10:33:10 smtp postfix/postscreen[28990]: CONNECT from [40.92.23.109]:10624 to [192.168.57.4]:25 Feb 15 10:33:16 smtp postfix/postscreen[28990]...

So the WebUI shows: Yes (550) and Exchange is: Get-RecipientFilterConfig Enabled : True

Hello, I'm looking at the address verification database and trying to understand how it works. From my understanding, it checks the backend server (Exchange 2010 in my scenario) to see if the recipient exists. If it doesn't, then it blocks sending it to the backend once the address has been...

How long does it take for this to rebuild? I reset it a few days ago, but it appears that Proxmox is still accepting non-existent emails, whereas before clearing of the database, it would block those. If I'm misunderstanding how the verification database works, please let me know. Thank you! :)

Great, I'll play with it! Thank you :)

I checked my logs and have very little at level 2, but I agree it is low. Here is a snippet of the same email that got through from the tracking center: Jan 15 03:18:22 smtp postfix/smtpd[1332]: connect from mail.matttteeer.com[195.177.95.195] Jan 15 03:18:23 smtp postfix/smtpd[1332]...

Thanks for adding some clarification to this. Just so I'm clear on my end, if I have the following for emails that are coming through: pmg-smtp-filter[1348]: 14285D60016BF0EFFD8: SA score=2/5 Then the following rule would be correct to block that level of SPAM and higher? Thank you! :)
