[sqwebmail] Session Timeout

[Serguey Forcade]

Hello:       After some time logged inside my email account I get this message logging me out,   Your request cannot be authenticated. Either your session has timed out, or your IP address has changed. If you are dialing in via a modem, this can happen if you get disconnected. After reconnecting, you must log in again.     I would like to know how can I modify the its value, I mean increase it. Thanks
