Setting up webmail.domain.com as default for new domains.

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_host.conf custom
cd custom
You'll need to edit the newly copied virtual_host.conf file and make the file look like (just add the blue to the end of whatever you currently have)

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.
