I have just confirmed with a direct test that Dovecot 1.0.0 using
Maildir does properly service 2 simultaneous IDLE sessions on the

have a manual IMAP session (telnet localhost 143...) and the messages
are popping up on the Palm in lockstep with the 'EXISTS' messages
kicking out on the telnet session. Meanwhile, Eudora is doing its
things from my Mac against the same mailbox (actually tossing
messages out of INBOX to other folders) and I'm pretty sure I left
Outlook running on my office machine and looking at the same mailbox,
so whatever flaky stuff it does is happening on whatever schedule it
uses as well...
Thanks. I have been using the same setup as you with no problems on my
existing server and loved it but have to say that the future of
Chatter looks questionable and my BB's get much better voice and
battery.
I saw the purchase of Chatter by Palm early this year as a positive
sign. After all, VersaMail is such a piece of junk and they really
needed something to answer Blackberry and the Windows Mobile push
approach.
As for battery life, I can attest to my Treo 650 running an IDLE
session being only a semi-portable device, particularly if I have the
BT radio on as well. I don't know how well the Blackberries do, but
it doesn't surprise me that they do better. I also can't recommend
that anyone with metered data usage use the Chatter IDLE route, since
that means a full-time data connection.
Note that one strong consideration for IMAP servers with more than a
handful of users is going to be dealing with the high concurrency of
a lot of eternal connections from the Blackberry server and from
other clients latched onto the same mailboxes. I suspect that one
reason some systems limit concurrent sessions is that they don't
have (or haven't be configured to use) efficient filesystem event
monitoring, and the alternatives are quite burdensome. In the case of
Courier, it looks like it still relies on SGI's FAM, an abandoned
project that doesn't really work well anywhere but Irix and Linux.
Dovecot has avoided that at the cost of having to understand each
system's unique approach to that issue.
Thanks for the insight.
