- Postal is a swift wrapper over libetpan.
- Libetpan handles all the low-level imap connection and parsing in a synchronous way.
- Postal wraps some features provided by libetpan and exposes them with an high-level asynchronous API.
- The high level API must be simple and comprehensive swift.
- Libetpan is provided in the repo as a pre-built static library for a better ease-of-use and easier CocoaPods distrbution
- Libetpan can be built from source using the shell scripts found in the dependencies folder.
Mailcore2 is a library wrapping libetpan providing a great set of features when interacting with mails.
The main drawback which made us start a fresh library is that Mailcore is an objective-c wrapper over a C++ wrapper over libetpan. These layers of complexity makes the library quite awkward to use in cunjunction with swift.
Swift provides a native way to interop with C and libetpan is fully portable. We hope that Postal may be ported to provide its feature set in a fully portable (server swift?) way.
