Description Tobias Mueller 2010-08-16 18:45:00 UTC
Summary:

SELinux is preventing /usr/sbin/ssmtp "open" access on /root/dead.letter.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by sendmail. It is not expected that this access
is required by sendmail and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2010-08-17 11:22:22 UTC
Miroslav,  I think we need to change the name of mail_forward_t to mail_home_t, then allow logwatch_mail_t to read mail_home_t.  And label dead.letter and .forward as mail_home_t.

I made this change in f14.
