Topic: Question regarding the use of blacklists

[imcintyre]

I'm using SME server 7.4 as my gateway and as an email server. I've enabled blacklists as per

Code: [Select]

The only contrib I have running on the server is:

If I wanted to add the Squidguard contrib to use other blacklists, would it create any problems? or should I get disable the email blacklists and control everything through Squidguard.

Thanks in advance for any help/advice given.

You seem to be confusing email rejection (based on RBL's & DNSBL's), and web access control via squid (using Squidguard or Dansguardian & associated blacklists).

The first allows qpsmtpd to reject mail from sources listed on Real Time Block or Blacklists etc (usually known spam or virus sources).

The second allows you to prevent local web browser users (who access the web via your sme proxy server), from accessing certain websites that are on specified blacklists (usually porn or inappropriate content sites).

In each case the "blacklists" contain quite different information, ie mail servers or web sites.

Mary;
Thx for getting back to me.

If I understand correctly;

• the email list blocking only concerns itself with incoming email.
• The squidguard or Dansguardian only concerns itself with outgoing connection attempts, i.e. if I use an email blocking list in squidguard, nothing will be blocked for my email.

Off-topic for this forum, which concerns only software installed from the SME server CDROM.

I was uncertain when I posted. Please feel free to move as seen fit.

....if I use an email blocking list in squidguard..

AFAIK that is nonsenical. You cannot use email blocking lists in squidguard.
Squidguard & Dansguardian block outgoing web access to web sites & content type.

The two methods (email Real Time Blocklists or squid web access type Blacklists) function independantly of each other and they do not impair or affect each other.
