  I'm glad to see I'm not the only one that wonders what sendmail.smtp is
  for...

  Anyway, onward -- I to switched over to the UofC standard.  Here, we
  have a "sendmail configuration program" that a bunch of us adopted a
  few years back which, by answering a few simple questions, will go 
  (re)configure sendmail for you... saved all of us having to maintain it,
  made sure we were all consistant (yeah, right!), and (BIG PLUS) saves
  new sys.admin. types here from the horrors of sendmail...  Well, it
  worked fine on all my machines EXCEPT the MIPS.  The fixed were :
  to get mail OUT of the MIPS  (thanks to R. LaT., MIPS/Sunnayvale)
  create the file /etc/sendmail.ok.  (This is actually in the /bin/mail
  manual page -- it should also be with the sendmail manual page)
  To get incoming mail, I needed to change my sendmail.cf so that the
  local mailer ("Mlocal") such that the argument vector called "rmail"
  instead of "mail"  (ie. "A=/bin/rmail").  This information in the 
  4.3BSD manual page mail -- not in the MIPS documentation.  Something
  aloing the lines that "rmail" is designed for use with UUCP and SENDMAIL
  for security reasons.  I suspect that because my pure BSD machines use
  "A=/bin/mail", that the BSD version of /bin/mail looks at the mail address
  and then calls "rmail" or "mail" as appropriate, whereas the Sys V (a.k.a
  RISC/os) version does not.... you may wish to try this.
