SquidGuard is a URL redirector used to use blacklists with the proxysoftware Squid. There are two big advantages to squidguard: it is fast and it is free.
Authentication
mod_auth_imap
mod_auth_imap is an Apache module that allows you to authenticate with an IMAP server. Since dspam is probably running on the same machine is your IMAP server, this is a viable option as well.
Apache Password File
When messages are passed through DSPAM, the recipient address dictates what user the statistics get logged to. The vpasswd for a domain can be used to generate a list of user IDs for authenticating into the DSPAM web interface.
This Perl script will generate an HTPASSWD file for all the users on your email system and place the resulting password file in /var/websites/dspam/htpasswd. Create a script file /usr/local/bin/vpasswd_to_htpasswd:
#!/usr/bin/perl
$htpasswdFile = "/var/websites/dspam/htpasswd";
$vuserinfo = "/home/vpopmail/bin/vuserinfo";
$vdominfo = "/home/vpopmail/bin/vdominfo";
@domainList = `$vdominfo -n `;
open(HTPASSWDFILE,"> $htpasswdFile") or die "Couldn't open htpasswdfile.\n$!\n\n";
foreach $domainName (@domainList) {
next if ($domainName eq "\n");
chomp $domainName;
@userList = `$vuserinfo -D $domainName -n`;
foreach $userName (@userList) {
next if $userName eq "\n";
chomp $userName;
$userPass = `$vuserinfo -p $userName\@$domainName`;
chomp $userPass;
print HTPASSWDFILE "$userName\@$domainName:$userPass\n";
}
}
close(HTPASSWDFILE);
Make the file executable:
chmod ugo+x /usr/local/bin/vpasswd_to_htpasswdApache Configuration
Edit the <VirtualHost> directive in /usr/local/apache2/conf/extra/httpd-vhosts.conf
AuthType Basic
AuthName "dspam Login"
AuthUserFile /var/websites/dspam/htpasswd
Require valid-userAutomatically updating htpasswd
Rather than manually recreating the htpasswd file whenever we make changes to the mail server, we'll use the Qmail-Updater service that was installed as part of validrcptto on the SMTP service.
Edit /service/qmail-updater/update-qmail and edit the $push_cmd:
my $push_cmd = "/usr/local/bin/vpasswd_to_htpasswd" ;- Log in to post comments

Various bits of code, scripts, and procedures were put together with information from John Simpson's qmail.jms1.net website. It's an excellent resource on managing and setting up a Qmail server.
