After tightening the spam controls some additional configuration may need to be done to Linux and winXP boxes for email functional tests to be able to pass. So far all OSX boxes have handled the change to the spam controlls without a problem.

Chandler uses the OS's configuration when determining what hostname to call itself when sending email. If a client does not uses a "fully qualified domain name" when sending email to smtp.osafoundation.org, the email will be rejected and Chandler won't be able to send email.

On linux, the command `hostname --fqdn` should return a complete 3-part hostname (ala mybox.osafoundation.org). If this command returns 'localhost', then the box is improperly configured. In /etc/hosts, the name of the host should not appear on the "127.0.0.1" line; it should only appear on the "127.0.1.1" line. If this command returns only your hostname (no domain), then update your /etc/hosts line to look like: "127.0.1.1 myhost.mydomain.com myhost".

On Windows, the command `ipconfig /all` should have a domain name in the "Connection-specific DNS suffix" of the network adapter in use. If that line is blank, then from the "Network Connections" control panel, click the "properties" button of your network adapter. Select "TCP/IP", and then click the "properties" button. Click "Advanced", then the "DNS" tab. Enter a valid domain name in the "DNS suffix for this connection" field and click "OK".

For Macs, so far 'it just works'. If you find you need to do something for macs to produce the fully qualified domain names for the tests please add instructions on how you did it here.
