Plesk has been installed and I've partly configured Plesk 8 in a VPS environment using CentOS 5. I set up 4 domains but am having problems accessing a new Wordpress install (getting 'SMTP server service is switched off') error message. I've hit the edge of my knowledge here and hope someone can finish. Things to do besides fixing SMTP issue would be to install necessary certificate(s) and any other fine tuning. Documentation of steps done would be appreciated.
