Getting Started

• DNS

  Before we begin, make sure DNS (mx record) is properly setup. If you were using "merchbox.com" as your virtual domain, here's how your host lookups would look after setting up dns:

  [shupp@ns1 toaster]$ host -t mx merchbox.com
  merchbox.com. mail is handled by 0 mail.merchbox.com.
  [shupp@ns1 toaster]$ host -t a mail.merchbox.com
  mail.merchbox.com. has address 216.234.249.114

• Remove existing smtp/pop/imap servers

  Now we must remove any existing installations of sendmail/postfix and disable pop/imap servers. To remove sendmail and postfix from an rpm based distribution, try this:

  sflj www.it55.com kg^&fgd

  rpm -e --nodeps sendmail postfix
  

  Unless you have other services that absolutely have to run on this machine, I recommend shutting down inetd or xinetd altogether and removing it from your startup scripts. The only thing you'll need (outside of what we're about to isntall) is ssh, which is probably installed already. This will likely shut off any pop3 or imap servers, as well as other unneccessary ports. Otherwise, disable them manually.

  To be sure that these services are disabled, try telnetting to ports 25, 110, and 143 and make sure your connections are refused.
