   Is this JNOS box connected to the Internet?  If so, you *WILL* want to 
add a few 'tcp access' rules to block incoming SMTP email.  JNOS *is* an 
Open Relay and will fill with SMTP spam attacks quite quickly which will 
drive it to its knees.  Do an 'smpt list' to see if there is a ton of 
pending email deliveries in the mail queue...

   My second suggestion would be to use the version 2.0 version of the 
JNOS code.  Maiko has fixed a number of bugs that were in the JNOS 1.11 
code when he released 2.0, and I HIGHLY suggest moving to it.  There is a 
link to Maiko's website in the "JNOS" section of the WWW.MI-DRG.ORG 

   Good luck!
