I am in the proccess of moving off of shared hosting to a dedicated server for this site and a few others I maintain. I am using Ubuntu 9.10 Server. This is a learning process for me. This is how I was able to configure my server to send email.
I installed sendmail
$ sudo apt-get install sendmail
$ sudo sendmailconfig
This will install sendmail on the server.
Once sendmail was installed I could send forms from my website, but it was very slow. In troubleshooting this I found a very helpful post in this thread about how to speed up form submissions with sendmail. A good explanation of why sendmail needs this can be found here. The solution is to modify the hosts file(found at
/etc/hosts), mine looks like this:
127.0.1.1 servername servername.localdomain loghost
You will need to replace the
servername in the above with your hostname. If you do not know what that is you can do:
to find out.
Hope this helps someone out.
