Script to enable SpamAssassin for new accounts
By default (if enabled), DA gives the User the option to enable spamassassin, but it is not turned on by default.
The above script can be used to also enable spamassassin for all existing accounts. You can create another simple script to do it called (for example) spam.sh with the following code:
#!/bin/sh
for i in `ls /usr/local/directadmin/data/users`; do
{
username=$i spam=ON /usr/local/directadmin/scripts/custom/user_create_post.sh
};
done;
exit 0;
Save this new spam.sh script, chmod it to 755, and run it once.
How to enable realtime blocklists (RBLs) with exim
To enable RBL blocking, as root, run the following:
cd /etc/virtual
rm -f use_rbl_domains
ln -s domains use_rbl_domains
This will setup the list of domains to be filtered to match the active domains list, so new domains added to the server are also included for the spammer IP blocking.
The RBLs will connect out to remote servers for each email, check to see if the sending IP is a spammer, and prevent that email from arriving. These lists are regularly updated, so they are highly effective.
Note that some lists also block entire ISP IP ranges, so if your clients are not able to send email, then can switch to sending email through port 587 instead of port 25.
or to disable RBLs, you can do the followig:
cd /etc/virtual
rm -f use_rbl_domains
touch use_rbl_domains

Uisng quotacheck program in DirectAdmin
DirectAdmin relies on the system quotas to return a value for how much space is being used.
DirectAdmin will run
If the “used” column is not showing anything, or users are not in the list, then you’ll need to run the quotacheck program:
Redhat:
/sbin/quotaoff -a; /sbin/quotacheck -avugm; /sbin/quotaon -a;
FreeBSD:
/usr/sbin/quotaoff -a; /sbin/quotacheck -avug; /usr/sbin/quotaon -a;
If are getting errors and no output is displayed for the repquota command, you’ll need to check your /etc/fstab file to make sure that it contains the rw,userquota,groupquota line beside the partition that is using the quotas.
Important: On Linux (Redhat/Debian), it’s usrquota,grpquota, and on FreeBSD it’s userquota,groupquota.

How to force SSLv3 ssl_cipher option in DirectAdmin
Edit - /usr/local/directadmin/conf/directadmin.conf file
directadmin.conf option called:
default value is internally ‘null’ (not used).
If anything is set for that variable (has to be added) then those values are passed to the ssl function:
so as to enforce which versions of ssl are allowed to connect.
The main reason to use this feature is to pass low level security scans which don’t like SSLv2.
A sample value for this option would be:
ssl_cipher=ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP

Specify the redirect host value when http is used on an https protocol
If you’ve enabled SSL=1 and the User enters http, then DA will give them the server IP redirect by default. This option will allow the admin to specify the value of the hostname in the redirect, which has an added benefit of forcing them to use the host that matches the certificate to valid ssl errors.
The directadmin.conf option will be:
ssl_redirect_host=host.name.com
The default setting is for the value to not be present in the directadmin.conf.
When it’s not present, the server IP will be used. With the option present, it’s value will be used (even it’s it’s blank) so make sure it only there if you want to use it.
