You’re migrating your site to your brand new Plesk server and your site doesn’t behave like it should. This is probably because of the default PHP settings that Plesk enforces.
Here’s how to take care of that.
After using your Plesk server for some time, you might want to, or have to change your server’s hostname. Assuming your server runs Fedora Core or RedHat, you’ll have to make changes in the following locations
As of Plesk 7.1.4, Plesk allows us to add TXT records in the DNS for a domain, thus allowing us to add SPF records. SPF is, in theory, a good way to stop spam. In short, SPF allows you to tell the world, which mailservers are allowed to send emails using your domain in the From address.
When building a site in PHP, you might want to put an index.html up to keep unwanted eyes away from your new site. The index.html however is overruled by index.php. Here’s how to fix this.
You might want to change the Horde webmail module in Plesk to behave more to your, or your company’s liking. Headers can be appended. The default footer (bah) can be removed, or changed to contain a disclaimer, quote, or simple message. The default stylesheet colours can be changed to be more uniform to your own website’s style, even bad words can be filtered from mails.
