Hi David,
don't know if you have set any timeouts for your tests such as
+) Email.MAIL_SMTP_CONNECTIONTIMEOUT
+) Email.MAIL_SMTP_TIMEOUT
+) Email.setSocketConnectionTimeout()
+) Email.setSocketTimeout()
The first two go into the email session for (javax.mail) while the two
others are set directly on Email - see
http://java.sun.com/products/javamail/javadocs/com/sun/mail/smtp/package-summary.html
Cheers,
Siegfried Goeschl
PS: Agreed on the fact the you should not hang indefinitely with a
default configuration

I set up a simple test to send 50 emails through google app's SMTP server
with a short delay between them (just testing to see what I'm allowed to
do).
I set this up by opening 50 threads and pausing at different intervals for
each thread.
I notice that I sometimes end up with a thread that hangs indefinitely on a
connection that seems to be hung, but never times out (see the thread dump
below for one such case, it's been left hung for> 10 min now):
Any thoughts on this? Kind of scares me to think what might happen to a
server posting emails in the background. I would expect network timeouts to
all be handled at least with a default value by a simplifying wrapper class
such as this is. Or am I missing some logic here maybe?
Thanks,
David
