Run a local sendmail/qmail/postfix - whatever, set the smtp server to localhost. The local MTA will queue and deliver when it can (right away or at the next queue run).

On your system:

# yum -y install sendmail
# chkconfig sendmail on
# service sendmail start


shoudl suffice.

I know bubke about CodeIgniter, so I cant help you there.

What's a common mechanism for emailing in the background?
I am writing my thesis in draft mode. 

\documentclass[dissertation,draft]{univthesis}


The univthesis is a dissertation template like a book. However, when I include figures, I only see the figure name and box enclosing it. When draft mode is removed, I get what I want. So, I was wondering if there is a way to display images even in draft mode. I have both .eps and .pdf files in the current directory.
