Sendmail Not Sending

[itchibahn]

My webserver uses sendmail 8.14.3 and php mail() just to send out mails from webforms. When I try to send, I noticed the message gets stored in /var/spool/mqueue, but does not get process. Please help.

Directory permissions should be ok:

drwxrwx--- 2 smmsp smmsp 512 Oct 13 17:12 clientmqueuev
drwxr-xr-x 2 root daemon 2048 Oct 13 17:12 mqueue

Test sendmail:

[root@virtual /var/spool/mqueue]# sendmail -v itchibahn@hotmail.com < /home/isot/tests/test.msg

Using php mail() shows little bit different log:
