Historically, I believe the problem has been caused by a 'perception'
issue between the client and the server in which the server e-s
misinterprets how many connections the client Tb is trying to have open
because of some discrepancy between the way Tb releases a connection and
how the server e-s expects to have a connection released.
The result of the miscommunication is that the server e-s thinks the
client Tb has too many connections already open, so it refuses to serve
up the next message.
If everything were actually happening the way the server and client
would like, e-s requires that
"The number of concurrent connections to the server is limited to 4"
.... and default Tb complies with:
mail.server.server2.max_cached_connections;2
.... since Tb refers to e-s news server as a mail.server.
I believe the mysterious miscommunication problem can usually be avoided
by configuring all news server accounts to uncheck 2 settings in the
account settings:
check for new messages at startup
check for new messages every xx minutes.
The e-s admin Ray Banana in the e-s support group has stated that Tb has
some kind of problem with releasing its connections; maybe it is
something about the way Tb caches, I don't know. I just know that I
don't have a problem and I uncheck the 2 checking for new messages which
doesn't actually apply to the Tb news server relationship anyway.
