Changing the Webmail Subdomain

Create a custom virtualhost template directory (if one does not already exist):

mkdir -p /usr/local/psa/admin/conf/templates/custom

Then, copy the current webmail configuration template:

cp /usr/local/psa/admin/conf/templates/{default,custom}/domainWebmail.php

Modify the custom template according to the customer’s needs:

subdomain=mail; sed -i.$(date +%s) "s/\(ServerAlias.*\"\)webmail.\(.*\)/\1$subdomain\2/g" /usr/local/psa/admin/conf/templates/custom/domainWebmail.php

Reconfigure all vhosts to use the new template:

/usr/local/psa/admin/bin/httpdmng --reconfigure-all

(Horde) You will also need to change a file in the Horde docroot so CSS works properly:

subdomain=mail; sed -i.$(date +%s) "s,\(preg_replace('/\^\)webmail\(.*\),\1$subdomain\2,g" /usr/share/psa-horde/imp/config/servers.php

(Atmail) Parallels has modified their default installation of Atmail to present a customized login box that automatically fills in the domain based on which URL was used to access webmail. When we changed the subdomain configuration, we broke this functionality – so we need to modify the login box so it works again:

subdomain=mail; sed -i.$(date +%s) "s,\(domain\.replace('\)webmail\(.*\),\1$su
