mailx package contains /bin/mail and /usr/bin/Mail and their man pages, but no mailx. The mailx package name indicates that installing it provides the mailx binary, but the actual /bin/mailx command can be found in redhat-lsb (as symlink to /bin/mail). And even though mail and Mail and mailx ends up being the same command then mailx has its own manpage - which can be found in the man-pages package. This is quite confusing and time-wasting when debugging mailx problems. I suggest that mailx should be selfcontained in Fedora 10 - or at least that status quo and its rationale be documented in the mailx package. Version-Release number of selected component (if applicable): mailx-8.1.1-48.fc9.i386
This seems to be ok - mail(1) is an man-page which is a part of mailx package and contains the description of mail command which is its part too. mailx(1p) is a part of man-pages and describe the the posix standard. mailx binary is the part of redhat-lsb.
For the record, * Wed Jul 30 2008 Dmitry Butskoy <Dmitry> - 12.3-1 - Place mailx to /bin/mailx, to avoid extra symlink in redhat-lsb package - /bin/mailx is now a base binary, another symlinked to it. thanks
