[Mailman-Users] Operating system error

[Krishna Rao SN]

Hi Lists,
 
Installed mailman on RH Linux 6.2 with apache & sendmail
 
Installation was successful without any errors.
 
Created a test list with users.
Now If I post a message to the list as auser, my message is delivered to the list server.
 
On the server if I type mailq command, the following error message shows:
 
# mailq
                Mail Queue (1 request)
--Q-ID-- --Size-- -----Q-Time----- ------------Sender/Recipient------------

                 (Operating system error)
                                   "|/home/mailman/mail/wrapper post toxeleia-he lp
 
Please advice
