Can you provide the ls -Z of your content in /etc/mailman/aliases

A advice:, use sealert to see a more human-readable approach to analyze the SELinux logs.

While waiting for a response from the list... I had just (discovered and) done a:

# grep postalias /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

But I haven't tested it yet.

On Fedora 14, I am setting up postfix and mailman.

I had this working once, but I decided to yum erase postfix and mailman
and redo the configuration to prove I knew how to recreate it.

Turns out I don't know how to recreate a working combination
because when creating a new list I now have mailman error log that
talks about:

command failed: /usr/sbin/postalias /etc/mailman/aliases (status: 1, Operation not permitted)

and a corresponding AVC error:

Aug 25 10:28:54 (null) (null): audit(1314282534.501:4326): avc: denied { search } for
pid=12121 comm=postalias name=postfix ino=295074 dev=dm-0
scontext=system_u:system_r:mailman_cgi_t:s0
tcontext=system_u:object_r:postfix_etc_t:s0 tclass=dir

Suggestions?

Fulko
