Thanks Paul and Daniel:
My procmail invocation is:
:0fw
* < 256000
| /usr/bin/spamassassin
And I see that I'm missing the lock (:) on this one, so I think my
comment about procmail writing a lockfile was in error. I looked into
spamc as an alternative - seems to work without a problem. Thanks for the
tip Paul.
The OS is Fedora Core 5, which I've been (somewhat blindly) updating with
yum (no extra configuration on yum - just running it out of the box). Yum
never complained, so I did not suspect that the system was partially
upgraded. To be explicit, I've not yet tried to upgrade to FC6 or FC7.
For the record, current status is
[root@parsnip ~]# rpm -qa | grep policy
selinux-policy-2.3.7-2.fc5
selinux-policy-targeted-2.3.7-2.fc5
policycoreutils-1.30.10-2.fc5
I guess the urgency on this is pretty low now that I've got the filter up
and running (via spamc). But I'm still curious as to what I would have to
have done if spamc didn't exist. I'm concerned about how many more SELinux
bullets I can dodge... :)
