Earlier I had a problem where whenever I tried to access the "Downloadable version" version of my list's archive. (The xxx.txt.gz has permission 600)

I managed to fix it via manually running $prefix/bin/arch <listname> archives/private/<list-name>.mbox/<list-name>.mbox

Shouldn't the bin/arch function be run automatically for each of my list? My list works fine in all other aspect (fingers crossed) except for 'downloadable archive'.

Did I miss a step elsewhere?

Thanks in advance
