A recent request to install mcrypt for a payment module for Sagepay led me to put together this quick how-to based upon my CentOS Plesk 9.x webserver.
Month: November 2011
Plesk has a built-in limit of 4 concurrent connections to IMAP from a single IP, so if you have more than 4 users – or more than 4 accounts which connect back to your Plesk server from any 1 IP – your users will get a Send/Receive error.
