1) A number of people suggested removing the quotes. When I change the
   line in the aliases file to 
   > our_group: :include:/usr/var/adm/sendmail/our_group.list
   the error from the mail-daemon looked like ...

  > While talking to mserv.rug.ac.be:
  > >>> RCPT To:<:include:/usr/var/adm/sendmail/our_group.list>
  > <<< 554 <:include:/usr/var/adm/sendmail/our_group.list>... Cannot mail 
  > directly to :include:s
  > 554 :include:/usr/var/adm/sendmail/groepje.list... Service unavailable
2) Someone else suggested removing the blank, so that the line looks like...
   > our_group::include:/usr/var/adm/sendmail/our_group.list
   but that makes no difference.
3) At one time, I suspected that there was an error because of an
   empty aliases.dir file ...
   > # ls -l /var/adm/sendmail/aliases.*
   > -rw-r--r--   1 root     system         0 Nov  6 13:08 aliases.dir
   > -rw-r--r--   1 root     system      1024 Nov  6 13:08 aliases.pag
   but that seems to be normal.
Anyway, I reconfigured sendmail from scratch (the configuration file
dated from a previous OSF/1 release), and found out that a piece of
code concerning the alias-translation has been changed. Since then,
everything works fine.
