I have been unable to track down any useful suggestions on how to solve
this problem:
I have Postfix 2.4.5 installed on a Fedora 7 system; it sends and
receives most email properly.
I can originate mail from this server (using "mail [EMAIL PROTECTED]")
which is accepted and delivered properly; this works
both as a normal user, and as root.
Anything in the dmesg output?
Anything like selinux running?
SELinux is running in enforcing mode, and I have created a local set of
rules to permit operations that were
formerly blocked. At present, there are no SELinux complaints
associated with this activity.
Further testing shows that if I turn off SELinux enforcing mode, then,
as you suggested, mail is handled correctly.
Some more Google searching turned up the notion of "DontAudit" rules;
apparently, for some rules, permission is
denied, but no AVC message is produced. This, of course, makes
debugging difficult. In more recent releases
than the one I have, there is apparently a way to block this behavior,
so that one has a chance of developing rules
that will permit the access needed. Oh well.
