They send commands and get no reply (but the command was done) or they send
messages and nothing happens at all?  You may have to query the Site Admin to
look in the LISTSERV log file to see if the messagaes are actually received by
LISTSERV.  If they are not, then there is a mail problem somewhere.

If they send the command and the command is executed but they get no reply then
the problem is the blank RFC821 MAIL FROM:<> issue (and their ISP is not
compliant with internet mail standards).
See http://www.lsoft.com/lsv-faq.html#5.16

To test this have then send 2 commands in one message to LISTSERV@...

message:   THANKS
           INFO listname

They should get 2 responses.  If the get only a response to the second command
(INFO about &LISTNAME) then this is the problem.  The reply to the THANKS
command is sent with a MAIL FROM:<>  the reply to the INFO is sent with
MAIL FROM:<owner-listname@...>
