=========================================================================== $NetBSD: MESSAGE,v 1.7 2012/12/20 20:38:46 jnemeth Exp $ To use "${PKGNAME}" as the system's mail transport agent you have to install "${PREFIX}/share/examples/sendmail/mailer.conf" as global mailwrapper configuration file. The command below will do that for you: ln -fs ${PREFIX}/share/examples/sendmail/mailer.conf /etc/mailer.conf You should also add a line to /etc/mtree/special.local so you won't get a complaint in the daily insecurity e-mail like this: ./etc/mailer.conf type=link mode=0444 If you are changing the database format used by sendmail you must run "newaliases" and "makemap" in order to re-create the databases. You may also need to install (and/or customize) the configuration files for Sendmail before it will be operational. "cd" to the directory ${PREFIX}/share/sendmail/cf and read the file README for instructions on creating and installing configuration files. NOTE: If your system doesn't have mailwrapper and/or it won't install on your system, then you will need to move aside system supplied binaries and replace them with symlinks to the binaries supplied with sendmail. The most important of these is the sendmail binary itself. This is typically located at /usr/sbin/sendmail or /usr/lib/sendmail. These will need to be moved aside, and you will need to create a symlink from /usr/sbin/sendmail to ${PREFIX}/libexec/sendmail/sendmail. This is required because most third party apps (or, even system supplied apps) will look for sendmail at one of the above locations. There are a variety of other apps such as: editmap, hoststat, mailq, mailstats, makemap, newaliases, praliases, purgestat, and vacation. You can deal with these either by having ${PREFIX}/bin and ${PREFIX}/sbin at the beginning of your PATH, or creating symlinks. hoststat, mailq, mailstats, newaliases, and purgestat are just links to sendmail. ===========================================================================
