Does java mail transport.connect(..) method have limitations on the no of threads that can use this connection. I am creating a component for asynchronous emailing that i can use for my self and also provide it to the java community.I have a main bean that can be instantiated with session scope later for each invocation to send method a separate thread is rolled which uses the same connection created by main bean.But it seems after a certain no of threads i get a MessagingException-- too many errors on this connection --socket write error--closing --cant send command to smtp server.Is this a limitation of the java mail or the no of threads the socket can handle.what is RFC822-compliant stream.How can i avoid this.    More>>
