Created attachment 334636 [details] Patches ebuild to install symlink to /usr/bin The mail-mta/msmtp ebuild does not install a symlink into /usr/bin if the mta useflag is set. It does however install one to /usr/sbin but this is obviously useless to non-root users who typically do not have that directory in their PATH. Given that ssmtp does not install the sendmail symlinks into /usr/sbin and instead favours /usr/bin - msmtp should do the same.
sendmail binary/symlink is typically installed under /usr/sbin. Non-root users are supposed to use the mail command. ssmtp was wrong to install a symlink under /usr/bin.
