Description Shweta Singh 2022-07-21 07:50:31 UTC

Description of problem:
Sendmail package is not part of RHEL8 Satellite and needs to be configured manually. 
Same works fine on EL7.

Version-Release number of selected component (if applicable):
6.11

How reproducible:
Always

Steps to Reproduce:
1. Configure Satellite 6.11 EL8
2. Sendmail binary is not present in EL8
3.

Actual results:
Sendmail binary is not present in EL8

Expected results:
Sendmail binary should be part of EL8 Satellite and shouldn't need explicit configuration.

Comment 1 Evgeni Golov 2022-07-21 07:59:47 UTC

Bit of context:
Foreman (and thus Satellite) defaults to using sendmail as the mail delivery method (alternative, it could use SMTP).
As Sendmail is not installed by default on EL8, this delivery method fails.

I've asked Shweta to post this BZ against the Installer, but am not 100% sure it is the correct place (but a good one to start!):
- we could also make packaging depend on Sendmail (or Postfix, or /usr/sbin/sendmail)
- in theory, it's not a hard dependency, as the user *can* chose to use SMTP
- we can use any /usr/sbin/sendmail, which can be also provided by Postfix and others (created by some 3rd party package)

Created redmine issue https://projects.theforeman.org/issues/35461 from this bug

Comment 3 Bryan Kearney 2022-08-31 12:05:02 UTC

Moving this bug to POST for triage into Satellite since the upstream issue https://projects.theforeman.org/issues/35461 has been resolved.

Comment 12 Shweta Singh 2022-10-03 10:45:41 UTC

Thanks Eric and Evgeni for actively working on this issue. 

Verified the fix on Satellite 6.12 Snap 13
Verification Steps:
1. Check if postfix service is enabled on satellite using command "systemctl status postfix" and enable the service if it is not. 
1. Update users email address to satellite fqdn to receive emails(Navigate to Adminiter --> Users)
2. Navigate to Administer --> Settings in UI 
3. Move to Email Tab and set the fields "Email reply address" to satellite hostname and "Send welcome email" to yes.
4. Verify "Email sent successfully" message on clicking "Test Email"
5. Verify the email received on email address configured in users email address(in /var/mail/root).

Note: Postfix service should be enabled and included as a part of email configuration in the documentation.
