Postal is a swift framework providing simple access to common email providers.



## Example



### Connect



```swift

let postal = Postal(configuration: .icloud(login: "[email protected]", password: "mypassword"))

postal.connect { result in

    switch result {

    case .success:

        print("success")

    case .failure(let error):

        print("error: \(error)")

    }

}

```



### Search



```swift

let filter = .subject(value: "Foobar") && .from(value: "[email protected]")

postal.search("INBOX", filter: filter) { result in

    switch result {

    case .success(let indexes):

        print("success: \(indexes)")

    case .failure(let error):

        print("error: \(error)")

    }

}

```



### Fetch



```swift

let indexset = NSIndexSet(index: 42)

postal.fetchMessages("INBOX", uids: indexset, flags: [ .headers ], onMessage: { email in

    print("new email received: \(email)")

}, onComplete: error in

    if error = error {

        print("an error occured: \(error)")

    }

}

```



### Want to debug your IMAP session ?



```swift

postal.logger = { log in

    print(log)

}

```



### What about Mailcore ?



Postal does not address the same goal as MailCore. You can take a look at our thoughts in the [TechnicalNotes][] document.



### Provider quirks



Email protocol is standardized. However providers implementations often provides extension or variations of these standards.

We tried to build a document to synthesize working around these variations here: [ProviderQuirks][].



### Contributing



Postal has been a great effort and we could really use your help on many areas:



- Finding and reporting bugs.

- New feature suggestions.

- Answering questions on issues.

- Documentation improvements.

- Reviewing pull requests.

- Fixing bugs/new features.

- Improving tests.

- Contribute to elaborate the [Roadmap][].



If any of that sounds cool to you, please send a pull request!
