I received several responses about my sendmail problem, all saying
essentially the same thing. I am including the answer that best described
the situation.
Now about that root canal...

I had exactly the same problem on Sol2.4 when I bit the bullet and installed
sendmail 8.6.9. When sendmail receives a message from a remote system, it
invokes /bin/mail to forward it to the actual user. Sendmail includes
the command line option -r <return path> to the mail command line, so the
command becomes (say)
/bin/mail -r "fred@somewhere.com <Fred Nurk>" localusername
Because mail doesn't support the -r option, it barfs with the following error:
> mail: Options MUST PRECEDE persons
and returns error code 5.
(try the above command at the command line and watch the same error appear).
So to solve it, edit sendmail.cf, and go to the line which reads something
like: (it's in the MAILER DEFINITIONS section)
Mlocal, P=/bin/mail, F=lsDFMrmn, S=10/30, R=20/40,
A=mail -d $u
This specifies the local mailer, the F= option tells sendmail what options
to include on the command line.
I found this in the sendmail.cf which came with Sol2.4, so I just copied the
F= bit in and all worked fine. If you get the doc tar.gz file and take
a look at the op.ps postscript file, it explains what each of these options
really means, if you're interested!
Mlocal, P=/bin/mail, F=flsSDFMmnP, S=10/30, R=20/40,
A=mail -d $u
^^^^^^^^^^^^
Enjoy,
Jack.
