We use a number of 'organisational' email addresses in the system as follows:

admin[at]openvpms[dot]org - the main administrator email address

subscriptions[at]openvpms[dot]org - the subscriptions and store manager (set via http://www.openvpms.org/admin/store/settings/store/edit but also embedded in various store content)

funding[at]openvpms[dot]org - pledge emails are sent to this address (set via http://www.openvpms.org/admin/content/node-type/development-project/fields in the text of the 'Project funding' field)

webmaster[at]openvpms[dot]org - feedback etc from the contact page (set via http://www.openvpms.org/admin/build/contact )

These address are mapped to real people using the postfix-vmail-mysql facility. The mappings are most easily modified via http://openvpms.org/phpmyadmin - this is protected via an htaccess username and password as well as the required mysql username and password.  For obvious reasons these are not listed here. The mappings are held in the database 'mail' in the table 'forwards'. Note that if you modify the mappings, it is sensible to restart the postfix service in order to ensure that the changes are effective. To do this login to the command line and do:

sudo service postfix restart
