fetchLast and fetchMessages never return...

[ikemuc]

I try to access my IMAP server with this code, which is based on your demo code:

`

import Foundation
import Postal

class MailManagerPostal {
    var configuration: Configuration!
    
    fileprivate lazy var postal: Postal = Postal(configuration: self.configuration)
    fileprivate var messages: [FetchResult] = []
    
    init(hostname: String, userName: String, password: String) {
        log.debug("init called...")
        
        configuration = Configuration(hostname: hostname, port: 993, login: userName, password: .plain(password), connectionType: .tls, checkCertificateEnabled: false)

        log.debug("configuration created: \(self.configuration.description)")
        
        postal.connect(timeout: Postal.defaultTimeout, completion: { [weak self] result in
            log.debug("postal.connect completed.")
            switch result {
            case .success:
                log.debug("fetching messages now.")
                
                let indexset = IndexSet(0...100000)
                
                self?.postal.fetchMessages("INBOX", uids: indexset, flags: [ .fullHeaders ], onMessage: { message in
                    log.debug("message : \(message.header)")
                    self?.messages.insert(message, at: 0)
                }, onComplete: { error in
                    if let error = error {
                        log.error("fetch failed: \((error as NSError).localizedDescription)")
                    } else {
                        log.debug("connection successful")
                    }
                    log.debug("fetch complete.")
                })
                
            case .failure(let error):
                log.error("connection failed: \((error as NSError).localizedDescription)")
            }
        })
        log.debug("init finished.")
    }
}

`

Problem: The last message I see is "fetching messages now.". Then nothing happens any more. What's happening here? Where is my mistake? The credentials I use work with using mailcode2 without a problem.

Some more questions:

• How can I debug the IMAP requests?
• Where can I find a documentation of the API?
• Can I manipulate message, especially add custom headers to a message (or take a message, add custom headers, write it as a new message to the server and delete the old one...)?

Just a thought but I think asking for 100,000 messages might be a problem. Have you tried less?

The first try was exactly the demo code with fetchLast() with 50 messages. It didn't work. Then I tried fetchLast() with 3 messages. Then I changed it to fetchMessages... Always the same problem...

[matadan]

I had a problem which is fixed in version v0.4.1. fetchLast had a bug. See: #44 <#44>

Tested it with 0..10 just to make sure. Same problem.

I updated to 0.4.1 today, that didn't solve the problem...

[matadan]

My issue was fixed with 0.4.1 but it sounds like you have a different issue.

[ikemuc]

I shifted the initialization of postal to the init() method and now it works.

class KanbanManagerPostal {
var configuration: Configuration!

var messages: [FetchResult] = []

init(hostname: String, userName: String, password: String) {
    log.debug("init called...")
    
    configuration = Configuration(hostname: hostname, port: 993, login: userName, password: .plain(password), connectionType: .tls, checkCertificateEnabled: false)
    
    var postal: Postal = Postal(configuration: configuration)
[...]

Now there are only the other questions unanswered ;-)

• How can I debug the IMAP requests?
• Where can I find a documentation of the API?
• Can I manipulate a message, especially add custom headers to a message (or take a message, add custom headers, write it as a new message to the server and delete the old one...)?

@ikemuc To answer your questions:

- How can I debug the IMAP requests?
You can set a closure on a Postal instance to have IMAP logs:

let postal = Postal(configuration: ...)
postal.logger { log in
    print(log)
}

- Where can I find a documentation of the API?

Unfortunately there isn't yet an official documentation of the API but we documented every public functions that you can access through xcode but I agree it's not enough. Everything should be ok to add jazzy or something like that if you want to do it, PR are welcome ! :)

- Can I manipulate a message, especially add custom headers to a message (or take a message, add custom headers, write it as a new message to the server and delete the old one...)?

No, Postal was first designed in first place only for fetching messages, not manipulating them. But I don't think it would be hard to add such features since libetpan propose an API for that.

Your issue seems fixed so I close it. If you want new features, please submit an issue and we'll figure out how to implement them as quickly as possible 👍
