This would indicate that sendmail is not actually listening, you need to 
do the netstat commands in order to verify this (ps -ef tells you 
processes but you may (or in this case) may not be running a different 
daemon, as in my example, "tcpserver" would not show up in your grep as 
above)

The log message suggests that you are not actually running an MTA and 
this is your problem.

(mailer=relay and relay=[127.0.0.01] as well as "connection refused by 
[127.0.0.1] indicate the mailer is trying to use SMTP as a transport and 
failing as you are not running a listening MTA)

netstat -an | grep LIST | grep :25

If the above returns something then

netstat -anp | grep LIST | grep :25

Otherwise the problem is you are not running the MTA, try

service sendmail start
