[net.mail] what is sendmail and where can I get a copy?

bmg@mck-csc.UUCP (bmg) (08/05/85)

I am using an HP9000 running HP-UX (similar to III) and am running
readnews V2.10.2 and have just recently joined the net.  I continually
getting the error message "/usr/lib/sendmail" not found when I attempt to
reply to a message.  I know nothing of sendmail and would be very
interested in a copy if someone would send it to me.  

I am also interested in knowing who is "supposed" to be handling path
routing for the network.  Is it the user, the mailer program, a specific
path decrypting program or is it a combination of the above?  I see
people saying that users need only know the users name, site and domain of
whom they wish to send mail to, but they don't say where all the minor
information like the actual path is to be stored (:-)).  

If some one knows what's goiong on, would they please tell me?  Thanks,
I'll be willing to put the responces together if there appears to be any
other interest in the matter.
