[Mailman-Users] "Operation not permitted" when updating aliases in Postfix.py

[Sergey A Lipnevich]

Hi,

My mailman installation is mostly doing fine, but every time I create a 
new list, I hit an error while performing os.system(update aliases db) 
in Postfix.py. I'm not running a secure kernel. I  fact, when I do:

su - mailman
python -c 'import os; print os.system("<skipped>/postalias 
<skipped>/mailman/data/aliases");'

I get "0" (zero character) in the output, which means it's OK (?). How 
come it can't run when a web interface is used? Naturally, my Apache is 
not running under mailman's uid.
Thank you!
