how do I allow exim access to a socket in order to be able to do local 
deliveries to cyrus?

type=AVC msg=audit(1521179280.845:1920270): avc:  denied  { name_connect 
} for  pid=319 comm="exim" dest=24 scontext=system_u:system_r:exim_t:s0 
tcontext=system_u:object_r:lmtp_port_t:s0 tclass=tcp_socket

Yet again I could not find any documentation explaining how to do basic 
things like this :(  Selinux is more like a curse than anything else :( 
Why is there not even a good documentation?
