hi all
sorry , i think i miss the previous email

here is the output
ls -l `which mail`
lrwxrwxrwx 1 root root 22 12月 18 11:13 /bin/mail -> /etc/alternatives/mail

ls -l `which sendmail`
lrwxrwxrwx 1 root root 21 12月 18 11:12 /usr/sbin/sendmail -> 

  ls -l `which mailx`
-rwxr-xr-x 1 root root 390720 12月 17  2014 /bin/mailx

to Barry

i issue mail command on a Centos 6.5 which the mail version is 

and ,i did a further test last night ,

mailman did not accept those emails set their From address as the 
maillist address.

which means , for example , if my maillist address is abc at mailman.com
then mailman server will not accept those emails sent from 
abc at mailman.com to abc at mailman.com

and if abc at aliase.com is a aliase of abc at mailman.com

mailman server can accept those emails sent from abc at aliase.com to 
abc at mailman.com

even aliase.com and mailman.com are resolved to a same IP address.
