Hello everybody,

I have a problem with session timeout (need to log-in again) in WebMail after I changed IP address of the mashine.
Logout timeout does not corespond with any parameters like
service.http.sessiontimeout = 7200
and it occurs after 8 minutes or something like this
And the value of mentioned parameter does not matter.

my other settings:
...
service.http.allowadminproxy = no
service.http.allowanonymouslogin = no
service.http.createtimestamp = ....... something ........
service.http.creatorsname = "....... something ........"
service.http.enable = yes
service.http.enablesslport = yes
service.http.fullfromheader = no
service.http.idletimeout = 15
service.http.ipsecurity = yes
service.http.maxmessagesize = 5242880
service.http.maxpostsize = 5242880
service.http.maxsessions = 6000
service.http.maxthreads = 250
service.http.modifiersname = "......something........"
service.http.numprocesses = 1
service.http.objectclass = nsmsgCfgHttp
,top
service.http.plaintextmincipher = 0
service.http.port = 80
service.http.resourcetimeout = 900
service.http.sessiontimeout = 7200
service.http.smtpport = 25
service.http.spooldir = (.........something......)
service.http.sslcachesize = 0
service.http.sslport = 443
service.http.sslusessl = yes
...

Somebody knows what could happend?
Whether maschine ip address changes can provoke problems like this?
I expect other reason but now I have no idea, what to do with this, and what am I to check.

Thanks a lot for any suggestions
