The library S22.Imap is a popular eMail handling package. But it was only available in .Net framework. I have rebuilt it in .Net Standard so that this library can be used in all versions of .Net. I do not own the copyright of the original source code. I built this package in .Net Stardard as I wanted to use it in .Net Core projects.
$ dotnet add package S22.Imap.StandardNo README available.
