Hello,
How can I see and then adjust if necessary the max number of files my
Fedora Core supports? I am thinking of user files, sendmail files in
the queue, etc the total number combined.

Files OPEN in applications or files ON disk (cq partition)?
The latter is a value determined by the file system and formatting
parameters OF that disk/partition, not dependant on the kind of Linux
(distribution) you run.
For ext2/3/4 with the "default" formatting it is normally 1 file for
each 16 KB of available space, see /etc/mke2fs.conf (at "inode_ration"),
as each file needs (at least) 1 i-node (directories and symbolic links
need one too, HARD links do NOT).
With the "df -i" command you get an overview of total/used/free i-nodes
on each file system that supports them.

As for open files in applications, that _is_ a kernel function (number
of available handles), but I wouldn't know if the Linux kernel
restricts that in any way or just allocates more memory for them).
Maybe in /etc/security/limits.conf
.
