Hello, I saw in /etc/passwd that mailman system user has shell access /bin/bash. I am using CentOS 7.3 x86_64 standard with WHM 62.0 (build 17). Can I disable shell access for mailman? Is it safe to be disabled? How should I disable shell access for mailman? On CentOS 5.11 x86_64 standard WHM 56.0 (build 46), mailman did not had shell access. Thanks.

  Hello, Mailman was refactored into an RPM as of cPanel version 58. The entry in /etc/passwd is by-design as certain mailman actions are ran as the "mailman" user. Thank you.

  Hello, Isn't unsafe for mailman to have shell access? Thanks!

  Hello, The mailman user is restricted to mailman-related actions. This is similar to the mysql system user. That said, if you are interested in improving the overall SSH security on your system, the following thread is helpful: [Tutorial] Interested in increasing the security of your server? Read this.
