Notification of new mail to client?

[Jim Archer]

Hello All...

I am installing Cyrus 2.1 on Debian Linux using the Debian packages.  I 
have noticed that Cyrus seems to not notify IMAP clients that a new message 
has arrived.  Other IMAP servers do this, so I was under the impression 
that it was a normal feature.  I looked through the conf files but didn't 
see a way to turn this on (assuming it is off).

Does Cyrus support this?

thanks

Jim
