Description Brian J. Murrell 2016-10-08 17:40:41 UTC
Description of problem:
When one configures their mail delivery agent flow to be MTA->Spamassassin->Cyrus IMAPd delivery one should not get AVCs.

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-60.el7_2.9.noarch

How reproducible:
100%

Steps to Reproduce:
1. Install and configure Postfix, Cyrus IMAPd and Spamassassin per local network
3. Configure Postfix to deliver via a pipe to spamc which then delivers using Cyrus' deliver tool as such:

Postfix main.cf:
mailbox_transport = spamc_cyrus

Postfix master.cf:
spamc_cyrus  unix -     n       n       -       -       pipe
  flags=R user=cyrus argv=/usr/bin/spamc -u ${user} -f -e
  /usr/lib/cyrus-imapd/deliver -m ${extension} ${user}

Actual results:
AVCs prevent spamc from using deliver to deliver the mail:
type=AVC msg=audit(1475947990.123:53197): avc:  denied  { write } for  pid=31467 comm="deliver" name="lmtp" dev="dm-7" ino=2488 scontext=system_u:system_r:spamc_t:s0 tcontext=system_u:object_r:cyrus_var_lib_t:s0 tclass=sock_file
type=AVC msg=audit(1475947990.123:53197): avc:  denied  { connectto } for  pid=31467 comm="deliver" path="/var/lib/imap/socket/lmtp" scontext=system_u:system_r:spamc_t:s0 tcontext=system_u:system_r:cyrus_t:s0 tclass=unix_stream_socket

Expected results:
spamc should be able to use deliver to deliver the mail to Cyrus IMAPd
