Yup, I checked on the Source RPM and the affected code it's in fact there, so it must have been backported as you've said. Thanks.

It says RHEL 8 is affected, but RHEL 8 comes with kernel 4.18, and according to https://seclists.org/oss-sec/2... the bug was introduced in 5.4-rc1, so I believe RHEL based systems (at least on stable version 8-based distros, like RHEL, Rocky or Alma) are not affected.

Gmail allows you to create any number (at least they don't seem to have any limit) of "filters". These are rules that allow you to manage your messages based on sender, recipient, subject, if the message has an attachment, if it has certain words, etc.

So this allows you to block some domains, if you'd like.
