All, I'm putting up a new email server, but I can't afford downtime when I switch servers. So, I've been writing a script that will take a CentOS install and turn it into a secure email server with Spam Assassin, Amavis-new, ClamAV and external relay using SASL authentication. The script is still *very* raw, and I'm relatively new to bash script writing. I still have some areas of work to do: - I need to incorporate the "alternatives" command to switch from sendmail to postfix, instead of using the redhat-switch-mail and changing it via gui. - I need to figure out how to automate the certificate generation. Right now I still have to type in a password at the prompt, as well as hit <enter> to accept the defaults - Some of my sed commands are kludgy. I'm still learning the ins and outs of sed - I have *no* idea whether or not Vipul's Razor is working or not. - I need to fix the yum "extras" section. - I need to improve the iptables handling. Anyway, if you guys'd like to take a look and make comments, I'm open to suggestions and whatnot. It's at: http://www.benjamin.weiss.name/mail-server.sh Thanks! Ben
