How To Install mailx on CentOS 8
Introduction
In this tutorial we learn how to install mailx on CentOS 8.
What is mailx
Mailx is an enhanced mail command, which provides the functionality of the POSIX mailx command, as well as SysV mail and Berkeley Mail (from which it is derived). Additionally to the POSIX features, mailx can work with Maildir/ e-mail storage format (as well as mailboxes), supports IMAP, POP3 and SMTP protocols (including over SSL) to operate with remote hosts, handles mime types and different charsets. There are a lot of other useful features, see mailx(1). And as its ancient analogues, mailx can be used as a mail script language, both for sending and receiving mail. Besides the “mailx” command, this package provides “mail” and “Mail” (which should be compatible with its predecessors from the mailx-8.x source), as well as “nail” (the initial name of this project).
