Hi,
We're running Ubuntu Server Gutsy and have exim4 installed and configured for sending emails from our internal machines. We're running into some issues with the time it takes to accept a message via SMTP. When we run the same delivery against our Exchange server the message is accepted in a fraction of a second however it takes about 5 seconds for the same process to occur with Exim. There are no DNS issues in the logs, the log entry just shows:

2008-11-27 13:49:28 1L5Wwa-0005K5-Fq Completed
The message is coming from a java application using javamail.
I've done a little reading and found it may be a setting in Exim to have background delivery of messages so the connection does not wait for delivery to occur before closing.
Is anyone able to point me in the right direction? Thanks.
