I apologize the the lack of detail in the post, I created it to prompt myself along when I performed installs at future dates, but never got around to filling it out.
- Perform a custom server only install of CentOS
- Do not install Mysql, dovecot or any other mail related software
- Install Sendmail via yum.
- Install Legacy software development, install Legacy software support. Install the basic development tools
- Once the install is complete; update and reboot
- Configure the users that SMS SMTP wants (create the users manually establishing their group memberships ahead of time)
- Install SMS SMTP using the smssmtp install binary and NOT “installer”
- Perform a typical install
- Reboot
- license and configure SMS SMTP to deliver local mail to 127.0.0.1 port 25
- Download and compile sendmail, install using Build install, this will overwrite the sendmail “fake” that SMSSMTP put into place.
- Modify the sendmail configuration to accept mail for your domain
- use chkconfig to configure sendmail to start at level 3
- reboot
- install dovecot, allow it to install mysql
- reboot
- You may have to configure dovecot to use Maildir correctly
- Done.
