deliver -- Mail Delivery Program

This program is a delivery agent designed for use with sendmail.
It is the local mailer program that actually delivers mail to the user
mailboxes.  The AT&T version of /bin/mail, which normally handles mail
delivery on System V, does not interact properly with sendmail, and the
Wollongong Group does not distribute one.

The recommended use is to link this program to /bin/mail and /bin/rmail.  In
this way, all mail will go through sendmail.  The only drawback to this 
approach is that some users actually use /bin/mail to read mail, and this 
program does not include that functionality.

To compile the program, simply type "make".  to install it, type
"make install" as root.  The program goes in /usr/local/lib/deliver
and is automatically linked to /bin/rmail.  The link to /bin/mail must
be performed manually, if desired.  Type the commands 
"mv /bin/mail /bin/omail; ln /bin/rmail /bin/mail".  The original AT&T
version of /bin/mail is saved in /bin/omail.  (If /usr/local/lib and /bin
are not on the same filesystem, the links will fail and you'll have to copy 
the file and set the permissions yourself).

this mailer line should be placed in your sendmail.cf file:
Mlocal,	P=/usr/local/lib/deliver, F=lsDFMm, S=10, R=20, A=mail -d $u

Incidentally, I have found two problems with the Wollongong Group's
version of sendmail.  Do not freeze the configuration file with the
command "/usr/lib/sendmail -bz" or things stop working (make sure the
file /usr/lib/sendmail.fc does not exist).  Also, the alias database
is never saved properly.  It is rebuilt each time sendmail is run.
So keep the /usr/lib/aliases file short.

Neither of these problems are present in my port of sendmail 5.58
available on ucsd.edu in u3b2/sendmail.cpio.Z.

Good Luck!
