Red Hat Satellite engineering is moving the tracking of its product development work on Satellite 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 "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. 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 "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-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:

I noticed that whenever I attempt to publish or promote a content view (composite or non-composite, with yUM or Docker based repos), there is a failed attempt to send an email notification:

2015-03-17 15:10:11 [W] Failed to send email notification satellite_promote_errata: Permission denied - connect(2)

My system is configured to use an smtp server (I will share my configuration in a second), with iptables running and selinux in enforcing mode.


Version-Release number of selected component (if applicable):

* Satellite-6.1.0-RHEL-7-20150311.1

How reproducible:


Steps to Reproduce:
1. Update your Admin user account with a valid email address 
2. Configure your Mail Preferences as per the attached screenshot)
3. Create a custom product and YUM-based repo and sync it
4. Create a content view (non-composite) and add the repo from above
5. Publish this content view while watching /var/log/foreman/production.log

Actual results:

[W] Failed to send email notification satellite_promote_errata: Permission denied - connect(2)

Expected results:

Comment 7 Stephen Benjamin 2015-03-18 15:35:11 UTC 
It's selinux, passenger needs ability to talk to 25

Comment 8 Lukas Zapletal 2015-03-18 16:23:22 UTC 
Interesting, we should have it in our policy already.

Workaround is to allow this port or permissive.
Comment 10 Lukas Zapletal 2015-03-19 10:18:53 UTC 
I think we only allow local send, if satellite6 was configured with a remote MTA via SMTP protocol, that will likely gets blocked.

Comment 14 Mike McCune 2015-03-20 21:46:03 UTC

Comment 15 Lukas Zapletal 2015-03-23 11:38:33 UTC 
Please apply the same patch, this one did not caused the getattr issue.
Comment 17 sthirugn@redhat.com 2015-03-25 20:44:58 UTC 
This same error happens when the Puppet error state notification email is triggered.

Note to QE: 
Check notification emails for 
1. Publish
2. promote
3. Puppet error state
