delprune and tlsprune

[itlistuser at rapideye.de]

Hi list,        
       
last night i had to restore all the messages in my inbox because cyr_expire     
 
and tls_prune, expired all messages in there. (the messages in subfolders were  
    
not touched).        
       
The man page of cyr_expire states that i have to have     
a /vendor/cmu/cyrus-imapd/expire file controlling the expiration. But i have    

not such a file. The parameter -E 3 shall tell cyr_expire to clean the     
duplicates database. Does it also affect the messages in the inbox?     
     
also i am using TLS to access imap. but i have no  tls_session_timeout    
variable set in /etc/imapd.conf, therefore i assume the default is used. but   
why does it remove all the messages from my inbox? afaik this command shall   
only remove timed out TLS sessions?   
   
at least for now i disabled tls_session caching with the line:   
   
tls_session_timeout: 0  
  
in /etc/imapd.conf 
 
      
the EVENTS part of the /etc/cyrus.conf:     
     
EVENTS {       
  # this is required       
  checkpoint  cmd="ctl_cyrusdb -c" period=30       
       
  # this is only necessary if using duplicate delivery suppression       
  delprune      cmd="cyr_expire -E 3" at=0400       
       
  # this is only necessary if caching TLS sessions       
  tlsprune      cmd="tls_prune" at=0400       
       
  # Uncomment the next entry, if you want to automatically remove       
  # old messages of EVERY user.       
  # This example calls ipurge every 60 minutes and ipurge will delete       
  # ALL messages older then 30 days.       
  # enter 'man 8 ipurge' for more details       
       
  # cleanup      cmd="ipurge -d 30 -f" period=60       
}       
       
also this is the first time that sth. like this happend. The server is running 
with this configuration since some months. 
 
anybody has an explanation for this behaviour and can tell me about? or can me 
point to some info to read about it? 
 
kind regards 
sebastian
