Amavis-new whitelist

  • 772

Hi to the Linux community. I'm coming from a Windows Server background so have mercy.

I'm attempting to whitelist some domains and although I know this isn't the best way of doing so its just a one off for a couple of domains so I thought it would be the quickest way of doing so. Current setup:

Amavis is used to pass emails off the ClamAV and SpamAssasin, currently I make changes in /etc/amavis/conf.d/50-user, as this will overide other settings.

Have created a whitelist file that looks like this:

.domaintowhitelist.com
.domain2towhitelist.com

In the 50-user config file:

Have tried variants like this:

read_hash(\%whitelist_sender, '/etc/amavis/whitelist');
read_hash(\%virus_lovers, '/etc/amavis/whitelist');

And restarting amavis after making those changes. Am I going about this the wrong way? Any help is appreciated.

  1. I do whitelisting at the MTA level (in my case postfix) rather than at the amavisd level. In my postfix/main.cf file, I have:

    header_checks=pcre:/etc/postfix/whitelist.pcre

    Inside whitelist.pcre, I have the following syntax:

    [email protected] FILTER  SMTP:[127.0.0.1]:10025

    where SMTP:[127.0.0.1]:10025 is the transport in master.cf that filtered mail is reinjected into the postfix system. My reasoning to do that is if certain messages are not to be checked for anything, I don't want amavisd to touch it.

  2. I never used a setup an external file. When I had to implement a whitelist, i simply used one of the form listed here:

    http://www.akadia.com/services/postfix_amavisd.html#Globally%20Sender%20Whitelists%20and%20Blacklists

    and especially this one:
    @whitelist_sender_maps = (['.example.org', '.example.net']);
