On my side Microsoft 365 generates NDR when I send the message to non existing email address using outlook online but does not generate NDR when sending a message to same non existing email address from thunderbird or other app sending emails through microsoft 365 SMTP server.
This sounds strange to me and I can't find a way to make it generate NDR aka bounce messages for messages submitted through SMTP.

Oh, those NDR message are actually generated but they are delivered to spam folder.
Even after disabling backscatter protection under advanced antispam settings it's working like that.
These automatically generated messages can't be manipulated using transport rules, so I have no workaround for this issue.

yeah, it's annoying, I remember one saturday morning when someone from office called me because i forgot to send something. I actually did but by made mistake in email address. Then I realized that I have delivery status notification in spam.

I've just discovered Michal Hrušecký is talking about @Delta Chat on the @OpenAlt conference.
The talk is in czech.
He had a similar talk a few weeks ago:
talks.openalt.cz/openalt-2025/…

DeltaChat - konečně inovativní IM OpenAlt 2025

S IM se roztrh pytel. Klasickěmu XMPP dnes konkurují služby jako Matrix, Signal, Telegram, WhatsApp a další. Je tu však jedna služba, která v této záplavě komunikátorů vyniká - DeltaChat.

I know this is not a support site or programming course but I can't figure this thing out. If you do know #rust perhaps you can give me a helping hand. I am trying to contribute to an app.

I'd like to parse ipv4 addresses given as command line argument values.
I have got two arguments accepting ipv4 address.
If I specify single such option all is fine.
If I specify both, I 'm getting error like this:

thread 'main' (624061) panicked at /home/peto/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/clap-3.2.25/src/parser/matches/arg_matches.rs:1879:13:
Must use `Arg::allow_invalid_utf8` with `_os` lookups at `[hash: A8F400C40154F09]`

This is simplified version of my code showcasing the issue:
```
use std::net::{IpAddr, Ipv4Addr};
use clap::{App, AppSettings, Arg, value_parser};

#[tokio::main]
async fn main() -> Result<(), Error> {
let mut app = App::new("Server APP")
.about("My super cool app")
.setting(AppSettings::DeriveDisplayOrder)
.setting(AppSettings::SubcommandsNegateReqs)
.arg(
Arg::with_name("socket")
.required(true)
.takes_value(true)
.long("socket")
.help("Unix socket path"),
)
.arg(
Arg::with_name("relayaddress")
.required(false)
.takes_value(true)
.long("relay-address")
.value_parser(value_parser!(Ipv4Addr))
.help("External relay ipv4 address used together with --listen-address to run behind a nat"),
)
.arg(
Arg::with_name("listenaddress")
.required(false)
.takes_value(true)
.long("listen-address")
.value_parser(value_parser!(Ipv4Addr))
.help("Local listen ipv4 address used together with --relay-address to run behind a nat"),
);
let matches = app.clone().get_matches();
if matches.is_present("relayaddress") & matches.is_present("listenaddress") {
let external_ip = IpAddr::V4(matches.get_one::<Ipv4Addr>("relayaddress").expect("Invalid address"));
let local_ip = IpAddr::V4(matches.get_one::<Ipv4Addr>("listenaddress").expect("Invalid address"));
println!("Listening on local IP: {local_ip}");
println!("Relaying through external IP: {external_ip}");
}}
```

@Federico Mena Quintero Oh, huge thanks for taking a look. Yes it's clap 3. It's not my decision, I'm attempting to contribute to an existing project so if I can make it work without major changes that might be helpfull. As I don't feel qualified for making decisions when it comes to this. I'm novice when it comes to #rust.
--socket argument is required, other two arguments are supposed to be used together and this condition is tested at runtime.
So if I specify all three command line arguments, I am always getting that error.
I have attempted using os::str and casting but the issue remains. I am simply compiling the app with cargo build --release.
Have you been just adding stuff I may have overlooked when trying to simplify for posting or did you actually changed something please?

@Federico Mena Quintero I've figured it out finally. The issue was not parsing ipv4 addresses but using matches.from_os() on the socket argument.
I have changed it to use std::path::PathBuf and it's working fine for me now.
Huge thanks for friendly hint and looking at my code.
