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.

Fixed In Version: quota-3.17-18.el6
Doc Type: Bug Fix
Doc Text:
Cause If quota limit has been exceeded on machine where warnquota tool enabled to send warning e-mails and superused did not change the default warnquota configuration. Consequence E-mails from <root@myhost.com> address are being sent. This can trick recipient to replay to invalid address or e-mail bounces can be delivered to <root@myhost.com> mailbox. Fix Default warnquota configuration has been changed to use reserved example.com. domain. Result Warnings about exceeded quota limits are being sent from reserved domain that should encourage superuser to change it to proper value and even though it should not abuse anybody.

Description Petr Pisar 2011-02-28 14:01:41 UTC 
+++ This bug was initially created as a clone of Bug #680429 +++

warnquota sending mails from a valid Domain Name

Additional info:
A user gets mail from root
We can change it in /etc/warnquota.conf but myhost.com is a Valid Domain & Ideally it should not send mails from anyone's other domain, It is better to use root@localhost or root.

--- Additional comment from ppisar on 2011-02-28 13:03:07 GMT ---

Properly configured warnquota should set sender address to valid domain to be able to route SMTP bounces if original message cannot be delivered.

I see the problem with example configuration file kidnapping regular domain names. The same can be said about the phone numbers.

I will change them into RFC compliant example values.

--- Additional comment from ppisar on 2011-02-28 13:50:10 GMT ---

Unfortunately, ITU has no reserved prefix for example PSTN numbers. Keeping original ones.

RHEL-6 quota utilizes the myhost.com too.
