[comp.sys.sun] Don't use OR in sendmail.cf in 4.0.1

benson@odi.com (Benson I. Margulies) (05/15/89)

After an entertaining correspondence with sun software support, I have
been informed that OR is hazardous to your health. In particular, mail
that uses <> addresses can cause sendmail hangs and lost mail. This is
particularly true with -t to sendmail, which is used by MH if no place
else.
