Hi all,

i use Roundcube on a Proxmox Container with Debian / Testing a long time. Now aftern an upgrade to RC 1.6.9 works my Reverse Proxy Configuration not more.

When i call the local ip from the roundcube host with my browser works all as before after the upgrade, if i will connect over the proxy server to my internal roundcube host comes after the login an error message with denied access.

I use apache on both maschines (reverse and roundcube host)

What is the diffrent between these both versions with using reverse proxy?

My local config:

Some browser is requesting a file that doesn't exist. It looks like the user browser is encoding "?s=" in the url so the file doesn't load. Bottom line there isn't anything wrong with Roundcube or Nginx the problem is on the end users browser side.

Have 1.6.7
Get these errors in the nginx error log. What can be wrong

How to create an email address

Hi,

This is the first time i'm posting here. I've got a problem with Roundcibe 1.6.9 on PHP 8.1.

When i open an e-mail from ABN AMRO roundcube becomes completely unresponsive. The PHP stops responding and i can't open new instances in new browsers too.

I get this error in the log of roundcube:

[10-Jan-2025 10:49:51 +0100]: <ar25461d> PHP Error: cURL error 56: TCP connection reset by peer (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://www.abnamro.nl/favicon.ico in /var/www/html/roundcubemail-1.6.9/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php on line 276 (GET /roundcube/?_task=utils&_action=modcss&_u=tmp-889c566a8bee81fcc88394de583c97f7.css&_c=message-htmlpart1&_p=v1)

Anyone has any idea why failing to fetch an image crashes the whole PHP? Seems like this should not happen.

Any help is greatly appreciated.

Kind regards,

Tom

I have same problem, is any solution?

The issue is that you are trying to connect to localhost and PHP cannot validate your cert because the hostname and the CN on the cert do not match. see https://github.com/roundcube/roundcubemail/wiki/FAQ#problems-connecting-imapsmtp-server-via-ssltls

Given you are connecting to localhost I don't think you need SSL/TLS because its the local interface.

Anyone looking for similar plugin can use this: https://packagist.org/packages/nemavi/dnsbl
It was based on this code
Also thanks @rosali let me know your details can include in info

Hi,
I have completed setup of self-hosted mailserver based on Dovecot, Postfix and Nginx.
Using a mail client I can receive and send e-mails.

Then I deployed roundcube by installing these Debian packages:
roundcube
roundcube-core
roundcube-pgsql

I can open roundcube WebUI entering this URL: webmail.mydomain.com.

When I try to send an e-mail, I get this error message:
[08-Jan-2025 01:17:18 +0000]: <au41b3b7> PHP Error: fsockopen(): Unable to connect to ssl://localhost:465 (Unknown error) (POST /?_task=mail&_unlock=loading1736299038458&_framed=1&_action=send)

root@mail:~# nano /etc/roundcube/config.inc.php


The error is related to my roundcube configuration:
$config = [];

// Do not set db_dsnw here, use dpkg-reconfigure roundcube-core to configure database!
include("/etc/roundcube/debian-db-roundcube.php");

// IMAP host chosen to perform the log-in.
// See defaults.inc.php for the option description.
//$config['imap_host'] = 'localhost:993';
$config['imap_host'] = 'localhost:143';

// SMTP server host (for sending mails).
// See defaults.inc.php for the option description.
$config['smtp_host'] = 'localhost:465';


After modifying the config by disabling certificate validation the error is not reproducible.
$config['smtp_conn_options'] = array(
    'ssl' => array(
        'verify_peer'       => false,
        'verify_peer_name'  => false,
    ),
);


However I want to use SMTPS: 465/tcp that is working with any other mail client.

Please advise how to fix this issue.

the error is not reproducible.

However I want to use IMAPS: 993/tcp that is working with any other mail client.

Please advise how to fix this issue.
