still cannot configure Archiva mail under Tomcat - jakarta-mail

Question

I have already looked here,
sending mail to a configured smtp server
and here,
http://www.questionhub.com/StackOverflow/2592434
and also the sendmail spec Appendix A,
but the answers just aren't helping me.
I have Archiva running under Tomcat 5.5.27 under Windows Vista, start up is fine but mail keeps crashing.
Have played with this config over a dozen times and am not getting anywhere (not sure why GT and LT signs are disappearing in my Resource tag):
Resource name="mail/Session"
auth="Container"
type="javax.mail.Session"
mail.transport.protocol="smtp"
mail.smtp.port="25"
mail.debug="true"
mail.host="mail.yyy.xxxx.edu"
mail.smtp.host="mail.yyy.xxxx.edu"
From the other threads it is UNCLEAR where to put a security.properties file. Under Tomcat does it go under \conf or does it go under \conf\Catalina\localhost?!? I have tried both - no luck!
The contents of my security.properties file is currently:
email.address.from=barretta#yyy.xxxx.edu
email.validation.subject=Archiva Maven Repository
The error message of the hour is:
Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 553 5.5.4 ... Real domain name required for sender address
(SABRE is the name of my machine.)
Once I click the button to register in the Archiva webapp, DEBUG from Tomcat stdout is:
DEBUG: getProvider() returning javax.mail.Provider[TRANSPORT,smtp,com.sun.mail.smtp.SMTPTransport,Sun Microsystems, Inc]
DEBUG SMTP: useEhlo true, useAuth false

at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
then a stack exception...
I can take the same mailapi jar I have under tomcat\common\lib and execute a simple Java standalone mail client that takes nothing more than FROM, TO, and SERVER and successfully sends email. SERVER value is same as mail host above, mail.yyy.xxxx.edu. No password/authentication. So I don't think it is my machine sabre, it is my Archiva configuration.
Please help.

Answer 1

I managed to solve the problem. The security.properties files lies buried deep within the archiva deployment under Tomcat, at:
\webapps\archiva\WEB-INF\classes\org\apache\maven\archiva. It is NOT under \conf!!!!
I added the property email.from.address as described in other postings.
Also whittled down the Resource element in \conf\Catalina\localhost\archiva.xml to:
<Resource name="mail/Session"
auth="Container"
type="javax.mail.Session"
mail.debug="true"
mail.host="mail.mii.ucla.edu"
mail.smtp.host="mail.mii.ucla.edu" />
I have other problems now, which I will post about separately.
