Hi team,

        I am trying to install mailman 3.3.4, the currently available

latest version at https://docs.mailman3.org/en/latest/install/virtualenv.html on RHEL 7.5.

        As part of the installation, I am not creating any user with the

name *mailman* and instead going with the *root* user only. Along with that I am using the directory */var/lib/mailman* as the root directory.

It is a very bad idea to run Mailman as root. If there were some vulnerability that would enable an exploit to run arbitrary code, you wouldn't want that code to run as root.

...

          Now, the issue is while I am trying to start the service, it

is showing the below error and the status looks like as following:

           # systemctl start mailman3

Job for mailman3.service failed because a configured resource limit was exceeded. See "systemctl status mailman3.service" and "journalctl -xe" for details.

          # systemctl status mailman3

           I can't understand where the issue might be.

What's in Mailman's mailman.log?
