This a simple, read-only email client. It is developed for my own use, most on the PinePhone - I couldn't find any dead simple clients with dead simple GUI that would also use only a small amount of resources, so I wrote this.
Most probably you don't want to use this, it is very tailored to my own needs.
But a few words:
- UI is in QML/Qt6
- mails are pulled using libCurl requests, through IMAP
- already fetched mails are stored in SQLite3 database
- mails are fetched periodically from a configurable set of folders
- mails are displayed with a WebView component
It has been only tried with GMail.
