monitor current number of imap users for cyrus-imapd 2.1.16

[John Wade]

As far as I know SNMP will give the number of persistent IMAP 
connections.  (same as your ps -ef | grep imap )  What you really want 
is the number of squirrelmail sessions.   Of course, since users do not 
have to use the logout link, you can't just count the /tmp/sess_*  
session files.    Maybe if you do a count of all session files with a 
modification time more recent then your squirrelmail session timeout you 
will get a reasonable approximation.   Try the squirrelmail lists to see 
if anyone has any ideas on this.
