+Many newer versions of Sendmail come with a restricted execution utility
+called ``smrsh'', which limits the executables that Sendmail will allow to be
+used as mail programs. You need to explicitly allow Mailman's wrapper program
+to be used with smrsh or Mailman will not work. If mail is not getting
+delivered to Mailman's wrapper program and you're getting an ``operating
+system error'' in your mail syslog, this could be your problem.
+
+
+One good way of enabling this is:
+
+
+
+
+
Find out where your Sendmail executes its smrsh wrapper
+
+
+
+ % grep smrsh /etc/mail/sendmail.cf
+
+
+
+
+
Figure out where smrsh expects symlinks for allowable mail
+ programs. At the very beginning of the following output you will
+ see a full path to some directory, e.g. /var/adm/sm.bin or
+ similar:
+
+
+
+ % strings $path_to_smrsh | less
+
+
+
+
+
cd into /var/adm/sm.bin, or where ever it happens to reside
+ on your system - alternatives include /etc/smrsh,
+ /var/smrsh and /usr/local/smrsh.
+
+
+
+ % cd /var/adm/sm.bin
+
+
+
+
+
Create a symbolic link to Mailman's wrapper program:
