[imp] Question about IMAP Quota on Redhat 7.3 using sudo

[Santiesteban Sifontes]

Hi all:
I'm testing the imp_show_quota , I've already added
the entry to sudo to permit apache execute quota
command but all I receive is "Quota not available" I
test the variables they're ok the function exec is
receiving all parameters ok, but it's not returning
nothing I think the problem is my integration of
apache - sudo- quota.
                             Any ideas??
                           Bye Aliet
