Sounds good... yeah, we definitely need to keep setting mail.smtp.from, 
so I'm glad that doesn't leak.

Since we've upgraded to JavaMail 1.3, there are some other proerties 
we'd want to set...
1. mail.smpt.connectiontimeout (socket connection timeout value in 
milliseconds, default is infinite timeout)
2. mail.smtp.timeout (socket I/O timeout value in milliseconds, default 
is inifite)
3. mail.smtp.sendpartial (If set to true, and a message has some valid 
and some invalid addresses, send the message anyway, reporting the 
partial failure with a SendFailedException. If set to false (the 
default), the message is not sent to any of the recipients if there is 
an invalid recipient address.)

Also maybe...
4. mail.smtp.localhost (Local host name. Defaults to 
InetAddress.getLocalHost().getHostName(). Should not normally need to be 
set if your JDK and your name service are configured properly.)  Maybe 
have this based on something in config.xml?

If possible, could try to set these as well and see if there are any 
memory leaks?... the 2 timeouts would be good to add to keep the 
delivery threads robust, as well as supporting partial message delivery 
(I can't believe people don't scream about this.)
