Description Jeremy Fitzhardinge 2013-12-18 22:24:01 UTC
Description of problem:
Repeatedly reported in /var/log/maillog by postfix.
SELinux is preventing /usr/sbin/postdrop from 'write' accesses on the directory /var/spool/postfix/maildrop.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that postdrop should be allowed write access on the maildrop directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep postdrop /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
