I recently purchased Plesk 2.5.2 for Windows, I am pleased with my purchase and have found that it does what it says 'on the box'. My problem is that I would like to install a separate email server on the same Windows machine that Plesk is installed on and run this instead of the mail server that comes with Plesk. I have switched off the Plesk Mail server in the Plesk Control Panel but Plesk appears to want to keep hold of posts 25 and 110 preventing the new mail server accessing these ports. Is there a way that I can release these ports for use by another email server whilst keeping the WWW server functionality in Plesk? Any advice / instruction would be appreciated.
