The other alternative for mailx is heirloom-mailx and I would strongly recommend that one over bsd-mailx. heirloom-mailx has lots more features, including the ability to specify MIME attachment files from the command line. In general, if you're wondering how to find out what the alternatives are for a given virtual package: $ apt-cache showpkg mailx ... Reverse Provides: mailutils 1:2.99.98-2 heirloom-mailx 12.5-4 bsd-mailx 8.1.2-0.20141216cvs-2 So, three choices. I only knew about the latter two.
