Short description: mail delivery agent with filtering abilities (set-GID=mail)
First things first, you will need access to a server or computer running CentOS 8. This guide was written specifically with a server running CentOS 8 in mind, although it should also work on older, supported versions of the operating system.
Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.
There are several ways to install lockmail on CentOS 8. You can use (links are clickable):
In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.
First, update dnf packages database with
dnf by running the next command:
sudo dnf makecache --refresh
After updating database,
You can install lockmail using
dnf by running the
sudo dnf -y install maildrop
Because lockmail is available in CentOS 8’s default
it is possible to install it from these repositories using the
To begin, update local packages database with
yum using the following command.
sudo yum makecache --refresh
Now can install lockmail package on your server/computer by running the following command:

To update all the packages available on the system:
If you want to update a specific package like lockmail in this example you should use the following command:
yum update maildrop
To downgrade a package to an earlier version:
yum downgrade maildrop
When you run the
dnf update, all system packages with available updates are updated.

the argument to the dnf update command.
dnf update maildrop
To uninstall only the
lockmail package you can execute
sudo dnf remove maildrop
maildrop is a mail delivery agent (MDA), a program which reads a mail message from standard input and then delivers the message to your mailbox. maildrop can deliver mail both in mbox and maildir storing formats. It can read instructions from a file, directing it how to log deliveries, and how to filter incoming mail, for example to deliver mail to alternate mailboxes, or forward it somewhere else, or pipe it through external programs. It performs all the same functions as procmail, but unlike procmail, maildrop uses a structured filtering language which is a bit easier on the eyes. Other differences from procmail include not skipping syntax errors in filter files (instead deferring the mails for later processing) and being more resource-efficient when processing mails (not loading large messages right into memory). maildrop in this package sets its permission to "rwxr-sr-x" (set-GID) and is owned by "root:mail". maildrop also comes with the following additional programs: * reformail, an e-mail reformatting tool, which can detect duplicate messages, manipulate message headers, split mailboxes into individual messages, and generate autoreply messages * maildirmake, which creates maildirs, and maildir folders * deliverquota, which delivers mail to maildirs while taking account software-imposed quotas * reformime, a utility for reformatting MIME messages * makemime, which creates MIME-formatted messages of arbitrary complexity * lockmail, which creates dot-locks, file locks, and C-Client folder locks * mailbot, a MIME-aware autoresponder utility
You now have a full guide on how to install
yum package managers.
