Sending local mail in AIX ?

Hello,

The task is to send mail to some local user from application running on localhost.
Looks like default mail server on AIX is sendmail, and it's not started on my servers:

# lssrc -a|grep mail
 sendmail         mail                          inoperative

But I am able to send local mail without sendmail running:

# mail
No mail for root
#
# mail root@localhost < file1
#
# ps -ef|grep mail
       root  808074       1   0 11:48:33  pts/0  0:00 send-mail -i -x root@localhost
#
# ps -ef|grep mail
#
# mail
Mail [5.2 UCB] [AIX 5.X]  Type ? for help.
"/var/spool/mail/root": 1 message 1 new
>N  1 root              Wed Aug 24 11:49  11/297
? exit
#

So now back to my task - I must configure local application(SAP to be exact) to send local mail - what should I do - configure sendmail for local operation or use method described above ?
Anyway how is that possible to send mail without sendmail running ?

thanks
Vilius

If you did not change anything with the sendmail configuration, it should work out of the box when you just start it with

startsrc -s sendmail
