sqwebmail 3.6.2 timeout issue

Hi all, 

When I compile sqwebmail with the softtimeout option, it STILL times out 
after 20 minutes. Is this a bug or have I not configured it properly? Or is 
there another way to set the timeout? 

Here's my configure line and I'm using sqwebmail 3.6.2: 

./configure '--enable-cgibindir=/path/to/cgi-bin' 
'--enable-imagedir=/path/to/images' '--with-authvchkpw' 
'--with-ispell=/usr/bin/ispell' '--enable-hardtimeout=86400' 
'--enable-softtimeout=14400' '--without-authpwd' '--without-authshadow' 
'--program-suffix=.cgi' '--without-authpam' '--without-authldap' 
'--enable-imageurl=/images' '--without-authdaemon' 


Thanks,
