Using spamassassin with selinux
Hi,
I'm still trying to get spamassassin to work properly with procmail
selinux (this is bug #172088, been open almost 50 days, still not
closed). I'm getting a bit tired of watching my spam system fail and
will probably revert to no selinux testing at all (selinux=0, like
almost everyone else) if this continues. 50 days is more than enough to
fix a reported problem.
I have the following entry in my procmail :
:0fw: .spamc.lock
* < 256000
| spamc
Now maildir logs show spamassassin is denied access to its own files
when selinux is enabled :
Dec 17 11:30:05 rousalka spamd[2681]: spamd: connection from
localhost.localdomain [127.0.0.1] at port 50637
Dec 17 11:30:05 rousalka spamd[2681]: spamd: setuid to nim succeeded
(yes spamd does setuids)
Dec 17 11:30:05 rousalka spamd[2681]: spamd: creating default_prefs:
/home/nim/.spamassassin/user_prefs
(spamd didn't see the pref files already existed - probably because of
selinux - so it tries to create it)
Dec 17 11:30:05 rousalka spamd[2681]: mkdir /home/nim: Le fichier
existe. at /usr/lib/perl5/vendor_perl/5.8.7/Mail/SpamAssassin.pm line 1467
(the system tells it to get lost, the file already exists)
Dec 17 11:30:05 rousalka spamd[2681]: config: cannot write to
/home/nim/.spamassassin/user_prefs: Permission non accordée
(and spamd is not allowed to write it)
Dec 17 11:30:05 rousalka spamd[2681]: spamd: failed to create readable
default_prefs: /home/nim/.spamassassin/user_prefs
likewise pyzor is dead
Dec 17 11:30:05 rousalka spamd[2681]: internal error
Dec 17 11:30:05 rousalka spamd[2681]: pyzor: check failed: internal error
and the autowhitelist can not be modified, because spamd can not create
a lockfile

tmp lockfile
