Defining Hostname to be used in Helo command

Question

Hi,
First of all I would like to say that I am not a Java developer or am too familar with JRE's, JDK's etc so please can all responses be in plain english!
We use an application supplied by HP called Quality Center. It is a Test Management/Repository tool and one of the functions it offers is auto email generation to keep users updated. QC is install on a Win 2003 server and it utilises JBoss.
Our company has recently changed our SMTP gateway so that any request that does not contain a fully qualifed domain name in the HELO command will be rejected. This is causing us a problem as the emails from the QC application is not using a FQDN. Below is the error we are seeing(I have replaced the server name below with locahost+):
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
     class javax.mail.SendFailedException: 504 5.5.2 <+localhost+>: Helo command rejected: need fully-qualified hostname
at com.sun.mail.smtp.SMTPTransport.rcptTo(SMTPTransport.java:926)at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:389)at com.mercury.optane.core.mail.CMailService.sendMail(CMailService.java:334)     wrapped in com.mercury.optane.core.CTdException: Invalid Addresses;
nested exception is:
     class javax.mail.SendFailedException: 504 5.5.2 <+localhost+>: Helo command rejected: need fully-qualified hostname
at com.mercury.optane.core.mail.CMailService.sendMail(CMailService.java:342)at com.mercury.td.saserver.api.logics.CAdminLogic.testSendMail(CAdminLogic.java:711)     wrapped in com.mercury.optane.core.CTdException: Failed to send mail. Please make sure that the server 'smtpgate.xxxx.com of type smtp is configured correctlyat com.mercury.td.saserver.api.logics.CAdminLogic.testSendMail(CAdminLogic.java:724)at com.mercury.td.saserver.web.CTdSiteAdminServlet.redirectTestSendMail(CTdSiteAdminServlet.java:742)
My question is simple - is there a Java or JBoss configuration parameter to set the FQDN? If not, where is the hostname being retrieved from?
The server has a fully qualified computername set, using DNS suffix, and we are not using Netbios over TCP. The hosts file has been updated to include the static IP address of ther server and the FQDN - does the 127.0.0.1 localhost line need to be removed?
HP are saying that the QC application does not store the FQDN anywhere in the application so I can only assume that the javax.mail class is using a default hostname value which is the localhost and not the FQDN.
Many thanks,
Steve

Answer 1

Are there any Java programs around that can retrieve the host name as this would be a good test.I guess it's so trivial I have to write it for you...
public class test {
    public static void main(String[] argv) throws Exception {
        System.out.println(java.net.InetAddress.getLocalHost().getHostName());
}If you can configure your system so that returns the expected value, your application should work.
"You can override what the SMTP provider uses by setting the session property mail.smtp.localhost" and "perhaps by setting it as a System property" - where would I find/do this? Is this a JDK setting or within the jboss config?It's a JavaMail setting. Without knowing how the application creates the JavaMail session,
I can't tell you where to set this, or if it's even possible to set it so that it will be seen by
the application. You could try setting it as a System property and see if that works. (And no,
I don't know how to do that with JBoss.)
