My home folders are mounted using fuse (from a moosefs server). procmail can not deliver to the Maildirs in these home folders, even though use_fusefs_home_dirs --> on From the log: Apr 4 08:19:29 ulmo setroubleshoot: SELinux is preventing /usr/bin/procmail from write access on the directory /home/mailwatch/Maildir. For complete SELinux messages. run sealert -l 7f33ea0d-5e3a-4209-92c9-7e2841cf86cd This is closely related to the similar dovecot report, now fixed - bug 800458. - Mike

This is strange since the Maildir is labeled home_root_t. Could you run restorecon -R -v /home To see if this changes labeles.
I'm not sure what happened. Anyway, I ran the restorecon, and it shows proper labels now. I'll attach the log in a moment. Here's the summary: [root@ulmo audit]# audit2allow -i mike.log #============= amavis_t ============== allow amavis_t var_yp_t:file { read open }; #============= procmail_t ============== #!!!! The source type 'procmail_t' can write to a 'dir' of the following types: # user_home_dir_t, mail_spool_t, tmp_t, user_home_t, var_log_t allow procmail_t fusefs_t:dir { write remove_name add_name }; #!!!! The source type 'procmail_t' can write to a 'file' of the following types: # mail_spool_t, user_home_t, procmail_tmp_t allow procmail_t fusefs_t:file { write getattr link read create unlink open };

Daniel: side issue - how do I force an audit.log rotation in a systemd world? "service auditd rotate" no longer works, of course.
I fixed them.
Michael I don't know ask on the audit list.
