1) You'll need to setup the virtualhost for apache. This can be accomplished by adding a 2nd virtualhost along side the domains main one.
cd /usr/local/directadmin/data/templates
cp virtual_host2.conf custom
cd custom
You'll need to edit the newly copied virtual_host2.conf file and add the blue to the end of whatever you currently have (the contents may vary)
Just be sure to add the new VirtualHost below the existing one.
|?DOCROOT=`HOME`/domains/`DOMAIN`/public_html|
|?OPEN_BASEDIR_PATH=`HOME`/:/tmp:/usr/local/lib/php/|
<VirtualHost |IP|:80>
|CUSTOM|
|?CGI=ScriptAlias /cgi-bin/ `DOCROOT`/cgi-bin/|
ServerName www.|DOMAIN|
ServerAlias www.|DOMAIN| |DOMAIN| |SERVER_ALIASES|
ServerAdmin |ADMIN|
DocumentRoot |DOCROOT|
|CGI|
...
...
</VirtualHost>
<VirtualHost |IP|:80>
ServerName webmail.|DOMAIN|
ServerAdmin |ADMIN|
DocumentRoot /var/www/html/squirrelmail
CustomLog /var/log/httpd/domains/|DOMAIN|.bytes bytes
CustomLog /var/log/httpd/domains/|DOMAIN|.log combined
ErrorLog /var/log/httpd/domains/|DOMAIN|.error.log
</VirtualHost>
Save and exit. Then run
echo "action=rewrite&value=httpd" >> /usr/local/directadmin/data/task.queue
/usr/local/directadmin/dataskq d
to rewrite the httpd.conf files.
2) You'll also need to setup the dns portition.
cd /usr/local/directadmin/data/templates
cp dns_a.conf custom
cd custom
echo "webmail=|IP|" >> dns_a.conf
This will setup the webmail A record for new dns zones. For existing dns zones, you'll have to manually add the webmail A record to point to the domains IP.
