11 months ago I have a similar issue. Had it working before on my old Nextcloud server. But now after setting up a new server I can't send any test emails.
ERRO[Oct 1 19:35:06.128] handler error: read tcp 127.0.0.1:1025->127.0.0.1:47632: read: connection reset by peer pkg=SMTPOpenSUSE Tumbleweed LXC in Proxmox Nextcloud 27.1.1 Proton Bridge 3.4.2

11 months ago @MrIngelborn I don't think these are the same issues. In my case, the error is "failed to parse message: failed to collect attachments: mime: invalid media parameter", which seems to be a bug in the way Proton Bridge parses the request.
In your case, the error is "read: connection reset by peer", which indicates that the TCP connection was abruptly terminated.
I'd suggest to open a different bug to investigate this.

I am also seeing the same error:

11 months ago I did some more testing with earlier versions of proton and nextcloud.
This issue was caused by nextcloud v26 combining the encryption and authentication configuration into one field.
Before v26 you could select Encryption: None but still put in credentials.
Now there is no None option only None/STARTLS. So when this option is selected and credentials are entered it expects to use STARTLS and then closes the connection when proton gives it a self-signed cert.
The solution will probably be to configure nextcloud to accept self signed certs. Instructions for this configuration are here.

11 months ago After more testing I have confirmed that the change to the way Nextcloud handles STARTLS is indeed the cause of the problem.
On Proton 3.5.1 and Nextcloud 27.1.1, this problem will go away if you add the following to your Nextcloud config at:
config/email.config.php
<?php
$CONFIG = [
"mail_smtpstreamoptions" => array(
'ssl' => array(
'allow_self_signed' => true,
'verify_peer' => false,
'verify_peer_name' => false
)
)
];You can also export Proton TLS cert, but that is more involved... and I'm not overly concerned about secure communication between my Proton Bridge container and my Nextcloud container.

I configured Nextcloud with this already: the fact that Protonmail is rejecting the content of the request shows that Nextcloud is accepting the certificate and sending a payload, so it's not the issue (in my case).

10 months ago @qdii can you post the Content-Type of the message you are trying to send? We have a known issue at the moment where if the filename or name attribute is not surrounded by quotes, it's considered invalid.

10 months ago For anyone else in the thread errors such as handler error: read ... can be safely ignored. This is just the IMAP client terminating the connection before we are unable to send them all the responses.

Thanks! That did solve my issue!

OK, I'll try to dump the communication so we can debug (by the way, having an option to do that on ProtonBridge CLI would be amazing).
It looks like Nextcloud's code to send a test email is here

Does the message have any other parts and/or attachments? The error in the root post refers to an attachments, but I don't see anything in those headers that would indicate there is an attachment.
