[imp] Auto logoff

[Tom King]

I'm doing a cursory search through the archives but haven't found this  
referenced yet. I'm constantly getting logged off with the message,  
"Your Internet Address has changed since the beginning of your Mail  
session. To protect your security, you must login again."

Is there an option to turn off this behavior? I know it's probably a  
good security measure but tends to be really annoying when I'm  
accessing webmail from outside my home network and get logged off  
after about 30 seconds.

Thanks!
Tom King
