Whitelists and blacklists messages

[Jlux]

Hi All

We are very happy with our proxmox and are pushing it out to clients as well. I just have a quick few questions.

1. I have noticed that there are 2 whitelists available. This first one is located in mail proxy/whitelist. The second is located in rules/whitelist/From: Whitelist/Whitelist. These do not seem to be connected, I.E. if I add a domain to one it doesn't show up on the other. What is the difference between these 2 whitelists? Also do I have to active the whitelist in the rule settings in order for the whilte to be used?

2. I know that proxmox uses blacklist to stop spam which is great, however is there any reporting in the real-time or search options to show that a email has been blocked by a blacklist (much the same as an emails shows up to be greylist) so that we can inform our clients.
Would it be possible to know the lists that proxmox uses for blacklisting too.

Thanks for your help.

Proxmox has 3 levels of whiteslist:

1. SMTP white list (means on SMTP level, if you list something here, no SPF, RBL, greylisting will happen)
2. Rule system
3. Personal white lists

Emails are processed in this order.

2. I know that proxmox uses blacklist to stop spam which is great, however is there any reporting in the real-time or search options to show that a email has been blocked by a blacklist (much the same as an emails shows up to be greylist) so that we can inform our clients.

statistics does currently not include RBL blocks - this feature is planned for one of the future versions.

we currently use the following lists for RBL on SMTP level:
sbl-xbl.spamhaus.org

Does this mean if you add emails to the smtp (mail proxy whitelist) all email listed will pass through even if the whitelist rule is in active?

emails are processed step by step. if you whitelist on the SMTP level, these messages are accepted on SMTP level and went for further processing to the rule system.

I guess I don't understand why you need two seperate whitelists. One for the global and one list for the rules? I would think once you added to the smtp whitelist that would be enough to allow the email address added to bypass everything.

there are many reasons, I just explain one scenario.

you SMTP whitelist a domain (e.g. one of your business partner) to avoid greylist and SPF problems.

so emails arrives directly and fast in the rule system, the rules doing spam and virus checks and delivers the emails to your users.

If you bypass the rule system, you will fire spam and viruses from these domain directly to your users which you never want.
