IMAP and Outlook problems - solved!
I managed to sort out the problem with IMAP, which seemed to disconnect outlook after about 10 minutes.
I NEED TO HIGHLIGHT THAT IT WAS NOT AN IMAP PROBLEM!!!
I also must say that UW-IMAP is working just perfect with xinetd.
If IMAP is running from xinetd it is very important to check xinetd.conf file. Depending on how many users are logging to IMAP server it is worth to adjust two parameters:
INSTANCES = 30 #is default, but depending number of users I changed that # to 60
cps = 50 10 #is default (SUSE 10.2) - I changed to 25 30
I think the number of running instances does not need any special explains, but it's worth to mention about cps.
cps is the parameter, which limits the rate of incoming connections. Takes two arguments. The first argument is the number of connections per second to handle. If the rate of incoming connections is higher than this, the service will be temporarily disabled. The second argument is the number of seconds to wait before re-enabling the service after it has been disabled. The default for this setting is 50 incoming connections and the interval is 10 seconds.
Hope that helps a little bit. Changing that two parameters solved my problems.
