A Swift framework for working with emails

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

Example

Connect

let postal = Postal(configuration: .icloud(login: "myemail@icloud.com", password: "mypassword"))
postal.connect { result in
    switch result {
    case .success:
        print("success")
    case .failure(let error):
        print("error: \(error)")
    }
}

Search

let filter = .subject(value: "Foobar") && .from(value: "foo@bar.com")
postal.search("INBOX", filter: filter) { result in
    switch result {
    case .success(let indexes):
        print("success: \(indexes)")
    case .failure(let error):
        print("error: \(error)")
    }
}

Fetch

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 ?

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.
