[SC-Help] Webmail Timeout

[Damien]

Is there any way to adjust the timeout on the webmail interface?

I find myself having to re-login several times in any given session, 
because the time required to review my daily (300+) held SPAM message 
subject load causes the system to complain: "Your Mail session has expired. 
Please login again."

I am sure that most people with <100 SPAM msgs daily have sufficient time 
to finish their work, but those of us with a larger mess to manage have 
different requirements.

Thanks!
