Joe,

I've modified line 66 in ssl.conf like this:

 SSLMutex default (instead of SSLMutex file:logs/ssl_mutex)

Now I'm able to send emails via squirrelmail, but SELinux is
still complying:

 audit(1103287307.997:0): avc: denied { search } for pid 7286
   exe=/bin/bash name=httpd dev=dm-0 ino=65076
   scontext=root:system_r:httpd_sys_script_t
   tcontext=system_u:object_r:httpd_config_t tclass=dir



Ok we can probably don't audit this.

I've installed squirrelmail via yum... and then added the
change-password plugin from its official web site. Of course,
to get the change-password plugin working, I had also to
compile and install poppassd (but I don't think this is the
problem).

Giuseppe, can you post your /etc/httpd/conf.d/ssl.conf?  This shouldn't
happen in the default mod_ssl configuration.



ugh,

Where is this mutex file being created? In the log dir? The probem
with this is it allows a hacker to unlink all the log files, if I
allow this rule.


mod_ssl (and various other bits of httpd) can be configured to use
various types of semaphore: these will all be SysV semaphores in the
default configuration, but in non-default configurations, can be files
with fcntl locking.  So the rule shouldn't be needed by default, I'm
confused why people are seeing this.
