RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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
