Looks like stupid to use this command to switch MTA. 🤓

I think the Debian's /etc/alternatives/ method could be applied to MTAs
or other similar packages.

For example, there's symlink /etc/alternatives/editor => /usr/bin/vim.basic,
                                                         /usr/bin/emacs
                                                         ...

Similarly the Debian packager could add
/etc/alternatives/MTA => /usr/sbin/sendmail.sendmail
                         /usr/sbin/sendmail.postfix
                         /usr/sbin/sendmail.exim
                         ...

Yeah, I need a weird setting. 😎
