5.1 listserv
The listserv generator communicates with Listserv.  Its behaviour is adjusted in the [listserv] section of the configuration file with the keys:
     
host- The host where Listserv runs, optionally in format host:port
 user- The email address, that is used to authenticate towards Listserv
 password- The password used for authentication
 capabilities- The capabilities, the generated scripts shall stick to.  Check the documentation for the extensions parameter in the function listserv_getsieve_scripts in liblistserv. 
 
   When the host, user and password are not specified, the defaults are read from the liblistserv configuration file.
