June 2020: poolp.org, folder pinning and webmail work

TL;DR: Reworked my infrastructure at poolp.org, implemented folder pinning, worked on my webmail. Shout outs to my patrons ! As usual, a huge thanks goes to the people sponsoring me on patreon or github, the work in this post was made possible by my sponsorship. poolp.org infrastructure rework I decided to move my servers from online.net to vultr.com (affiliation link).
