How do I get sendmail working again

[Andrew Falanga]

HI,

I've gotten myself into a real fix at this point.  (This is a continuation of 
the thread I started, "sendmail is broken, how do I fix?")  I was trying to 
setup authentication based relaying using istructions at 
http://www.puresimplicity.net/~hemi/freebsd/sendmail.html.  I must first say 
that I was trying to get authentication based relaying working by using the 
instructions in the handbook under the title "SMTP Authentication."  The two 
set of instructions do overlap slightly.

Well, after following the instructions at the former link, sendmail will no 
longer start and is complaining with errors as follows from 
the /var/log/maillog file:

Someone asked me to post the result of doing, "sockstat | grep ":25" just 
after starting the sendmail process.  Well, here's that output:

whitbap# /etc/rc.d/sendmail start
Starting sendmail.
whitbap# sockstat | grep :25

I do know for a fact that it's sendmail that's killing itself.  Without 
anything else running related to mail (sendmail or dovecot) I wrote a little 
C program to open a socket and bind to port 25 and it works ok.  Please help 
me.  I have got to get this working for the church and at this point, I'm not 
sure how to make it work.
