How To Install up-imapproxy on CentOS 8
Introduction
In this tutorial we learn how to install up-imapproxy on CentOS 8.
What is up-imapproxy
imapproxy was written to compensate for webmail clients that are unable to maintain persistent connections to an IMAP server. Most webmail clients need to log in to an IMAP server for nearly every single transaction. This behaviour can cause tragic performance problems on the IMAP server. imapproxy tries to deal with this problem by leaving server connections open for a short time after a webmail client logs out. When the webmail client connects again, imapproxy will determine if there’s a cached connection available and reuse it if possible.
