Java EE (Java Enterprise Edition) General Discussion

Hello

I was getting this error with my initial attempts to send myself an email using JavaMail:

javax.mail.MessagingException: 501 Syntactically invalid HELO argument(s)

After hunting around for a while I came across references to doing this:

props.put( "mail.smtp.localhost", "localhost" )

So I tried it, and it works!

I'm happy about that, but I would like to find out why? I just cannot seem to find an answer anywhere.

I run Windows XP, and my hosts file has not been changed - localhost is still there, as shipped. When I call this:

InetAddress.getLocalHost().getHostName()

I get the $COMPUTERNAME value for my PC which happenes to be "HARRY_PC".

My real concern is what will happen when I deploy my application to other machines - is this little 'hack' likely to break things?

Hmm...

Many thanks!
