if you could please help.
I've installed openemm on Centos box. mysql, python, jdk, sendmail, etc all seem to be running.
I have my url listed as local host so when I use the borweser I can login to openemm using http://localhost:8080
I even created an email campaign and a mailing list. But when I hit send mail, nothing happens

The recipients dont get any email. There is nothing in the var/spool queue etc area.
Where should I look?
I am stuck in what I should be using as host? Can I still use localhost:8080 in my preferences to send email? Are there error logs?
Thank you!
