:*****  Plugin bind_ports (99.5 confidence) suggests  *************************
:
:If you want to allow /usr/bin/perl to bind to network port 30221
:Then you need to modify the port type.
:Do
:# semanage port -a -t PORT_TYPE -p udp 30221
:    where PORT_TYPE is one of the following: .

:*****  Plugin catchall (1.49 confidence) suggests  ***************************
:
:If you believe that perl should be allowed name_bind access on the  udp_socket 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 spamassassin /var/log/audit/audit.log | audit2allow -M mypol

Comment 3 Miroslav Grepl 2013-01-28 11:10:41 UTC
Did you setup 30221/udp port for spamassassin?

There is a boolean for this

# setsebool -P spamassassin_can_network 1
