Hello List,
after the last update I have a selinux "Problem" with dovecot.
My system is a centos 7.

After a new start from dovecot selinux block a connection.

executing:#012# ausearch -c 'dovecot' --raw | audit2allow -M my-dovecot#012# 
semodule -i my-dovecot.pp#012

is this a bad Error?

When I install this local Policy i have a Problem with selinux wrong policy.

sealert -a /var/log/audit/audit.log

tcontext=system_u:object_r:proc_security_t:s0 tclass=file permissive=0
**** Invalid AVC allowed in current policy ***

100% done
found 0 alerts in /var/log/audit/audit.log

Can any tell / help me for a correct installation?

mit freundliche Grüßen / best regards,
