I'm having trouble with net.mail.send. Trying to send email from/to 

my .mac account I'm getting this error message:

com.sun.mail.smtp.SMTPSendFailedException: 556 5.1.0 Invalid From 

    at com.sun.mail.smtp.SMTPTransport.issueSendCommand 

    at com.sun.mail.smtp.SMTPTransport.finishData(SMTPTransport.java:1321)

I have no idea why georghajdu@mac.com is generating this message.

Also, I noticed that authentication wasn't implemented. Is this on 

the author's to-do list? This would be nice!

It's quite possible that the error is a consequence of not
authenticating, if that's what the SMTP server expects (the status of
response codes > 554 is sufficiently murky to not be clear with a quick
