5 months ago Hi,
This error happens whenever I try reading mails with this (drafty) rust implementation:
use imap;
use native_tls;
use dotenvy::dotenv;
use std::env;
use crate::mail;
struct ImapClient {
session: imap::Session<native_tls::TlsStream<std::net::TcpStream>>,
}
impl ImapClient {
fn new() -> ImapClient {
let mut session = mail::read::mailer();
ImapClient { session }
}
fn logout(mut self) {
self.session.logout().unwrap();
}
}
pub fn mailer() -> imap::Session<native_tls::TlsStream<std::net::TcpStream>> {
dotenvy::dotenv().ok();
dotenv().expect(".env file not found");
let user = env::var("USER").expect("USER not defined");
let password =
env::var("PASSWORD").expect("PASSWORD not defined");
let imap_host = env::var("IMAP").expect("IMAP not defined");
println!(
"connecting to imap server: {imap_host}, with username: {}",
user.clone()
);
let tls = native_tls::TlsConnector::builder().build().unwrap();
// we pass in the domain twice to check that the server's TLS
// certificate is valid for the domain we're connecting to.
let client = imap::connect((imap_host.clone(), 3143), imap_host, &tls).unwrap();
// the client we have here is unauthenticated.
// to do anything useful with the e-mails, we need to log in
let mut imap_session = client.login(user, password).map_err(|e| e.0).unwrap();
// we want to fetch the first email in the INBOX mailbox
imap_session.select("INBOX").unwrap();
imap_session
}
// pub fn read_mail(mut session: imap::Session<native_tls::TlsStream<std::net::TcpStream>>) {
fn read_mail(client: ImapClient) {
let mut session = client.session;
let messages = session.fetch("1", "RFC822").unwrap();
let message = messages.iter().next().unwrap();
// extract the message's body
let body = message.body().expect("message did not have a body!");
let body = std::str::from_utf8(body)
.expect("message was not valid utf-8")
.to_string();
println!("body: {}", body);
// session.logout().unwrap();
}
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn test_read_mail() {
let mut client = ImapClient::new();
read_mail(client);
}
}Equally when sendin mails

Rarely I am facing an exception that occurs when using greenmail:
According to the message in the Exception and the line in the code ( https://github.com/greenmail-mail-test/greenmail/blob/master/greenmail-core/src/main/java/com/icegreen/greenmail/imap/ImapSessionFolder.java#L93 ), this seems to be a greenmail-internal issue, right?
Is there anything I can do to prevent this to happen or do you have plans to fix the TODO in the code causing this?
