Installing James 2.2.0 Information none Operating system used Windows XP Home Edition Version 5.1 SP 2 Software prerequisites Java 2 Standard Edition (J2SE) SDK, version 1.3 or higher. Note: If J2SE SDK 1.4.x is installed, please remove xerces.jar from Phoenix's lib dir. This is because J2SE SDK 1.4.x comes with xerces, and Phoenix may object to two versions in the classpath. Procedure Download and unzip james-2.2.0.zip e.g.: C:\Tools\james-2.2.0 Start James, enter command: C:\Tools\james-2.2.0\bin\run.bat You should see: Using PHOENIX_HOME: C:\Tools\james-2.2.0 Using PHOENIX_TMPDIR: C:\Tools\james-2.2.0\temp Using JAVA_HOME: C:\Tools\java\j2sdk1.4.2_01 Phoenix 4.0.1 James 2.2.0 Remote Manager Service started plain:4555 POP3 Service started plain:110 SMTP Service started plain:25 NNTP Service started plain:119 Fetch POP Disabled FetchMail Disabled If James is started for the very first time, it unpacks the contents of the C:\Tools\james-2.2.0\apps\james.sar file and creates directory C:\Tools\james-2.2.0\apps\james Make the following changes in the C:\Tools\james-2.2.0\apps\james\SAR-INF\config.xml file: Change the Remote Manager Service administrator account. The default login/password for the Remote Manager Service is root/root. For security reasons change this: <administrator_accounts>    <account login="jamesroot" password="jamesmysecret"/> <administrator_accounts> Set email services for a particular domain. If you want James to provide email services for a particular domain, for example mobilefish.com, add the following: <servernames autodetect="true" autodetectIP="true">    <servername>localhost</servername>    <servername>mobilefish.com</servername> </servernames> Enter the ip address of your DNS server. <dnsserver>    <servers>       <server>192.168.1.254</server>    </servers>    <autodiscover>false</autodiscover>    <authoritative>false</authoritative> </dnsserver> To find the DNS server, type: ipconfig /all you should see: DNS-servers . . . . . . . . . . . : 192.168.1.254 Note: If you have installed James on an development environment and you have not setup your own DNS server you can do the following: Open your hosts file: C:\WINDOWS\system32\drivers\etc\hosts Add the following lines: 127.0.0.1 smtp.mobilefish.com 127.0.0.1 pop.mobilefish.com Now you can still send out email to any address. However you can only receive email if it is send and received from within the mobilefish.com domain. See guide Setup mail client to communicate with James SMTP server.
