The linux server where exim service is running is under no load. 

The system is sending email successfully but is taking a long time to send each email. 

Basically if I telnet to localhost port 25 and then I try to send an email from there the response from the server is super slow. The mail application we have running there is taking more than 8 minutes to send 4 emails. 

Has anyone confronted this issue before with EXIM and maybe you might now what is the setting that is making EXIM wait so long for something. I am looking at the logs and I cannot see anything indicative of an error. Below a sample of the mainlog:
