Question with sendmail on CentOS

Question

I get an error when I restart sendmail on my CentOS server, and it can not send email out. The error is :

[root@centos sendmail-8.13.6]# service sendmail restart
close sm-client：                                           [success]

Answer 1

From the sendmail FAQ:

What does "class hash not available" mean?

I'd try to figure out if this install of sendmail was done with some customizations for some reason.

Post your sendmail.cf and we'll take a look.

Answer 2

What you post is odd, because when I restart sendmail on a CentOS 5.6 box, what I get is:

[madhatta@www ~]$ sudo service sendmail restart
Shutting down sm-client:                                   [  OK  ]
Shutting down sendmail:                                    [  OK  ]
Starting sendmail:                                         [  OK  ]
Starting sm-client:                                        [  OK  ]

Which makes me wonder if you're running some kind of hand-built sendmail - because the packaged version does. Before anything else, could we get the output of rpm -qf /etc/init.d/sendmail and the version of CentOS you're running?

Edit: thanks for those. Could you also confirm that you're not running any kind of hand-hacked sendmail, perhaps with rpm -qV sendmail?

Edit 2: in the light of dmourati's excellent observation, can we see what your sendmail is compiled with? A quick way to do this is to cut-and-paste (please, don't just retype) the output from sendmail -bt -d3,0.
