+
+#+BEGIN_SRC: bash
+export MAILINGLISTNAME=mailinglistname
+export MYUSERNAME=myusername
+export HOSTNAME=mydomainname.com
+export EMAILADDRESS=$MYUSERNAME@$HOSTNAME
+schleuder-newlist $MAILINGLISTNAME@$HOSTNAME -realname "mailing list name" -adminaddress $EMAILADDRESS -initmember $EMAILADDRESS -initmemberkey /tmp/mypublickey.txt -nointeractive

 *** With Bitmessage
 On your local machine (not the BBB) you can make a private mailing list which is difficult to censor and where there is no single point of failure.  This type of mailing list is known as a "chan".
