I'm working on the same issue, I use a CRM and send and receive and RoundCube I receive but like you get an smtp connection error
I found one error in the config, I miss spelled the database so I wasn't connecting even to the database but I still get an smtp error.

I'm also using virtual mail domains

Mi mail tiene bloqueados a todos los destinatarios que usan cuentas hotmail.com y no se como eliminar ese bloquea. Alguien me ayuda?
gracias

Hi !

I need tester for the next version.

I'm using Bootstrap v5.3.7 instead of the Bootstrap v4.x because of CVE-2024-6531.

Info here : https://www.roundcubeforum.net/index.php?topic=31434.0, https://github.com/roundcube/roundcubemail/issues/9633


So far it looks good but I can't test all plugins and options.

Thanks to tell me if the latest code works :

Understood. Thank you for the info.

Roundcube doesn't have filtering built and in. That needs to be setup on the mail server which it sounds like would require you to be able to login to cPanel.

Please tell me I can create and manage filters within RoundCube itself, and that I do not have to log into my hosts C-Panel to do so.

Hello, new forum member here with a newb question. I own a small business and would like to create folders for all my different customers. And I want to set up filters so that whenever a new email comes in from a specific customer, that email stays in the general inbox, but also is copied to their respective folder. That way when I need to find an email quickly I can just access that customers folder and search within it. I would be nice to have folders for every customer so that it groups all of their emails in one place, but I still want to have the main inbox function normally as well. I hope this makes sense.

I did see some info about setting up filters, but I cannot even find "filters" in RC. Can someone help, and make it really easy, because apparently I am not smart enough to figure it out. lol

Any help is appreciated! TY for reading.

Since your using Nginx and its complaining about an upstream issue I assume your using PHP-FPM. Have you checked those logs?

Mmm, the server is Nginx and I have finally found a log that sends an error when the RCM editor is invoked. It is in Nginx and it reports that:

2025/08/19 11:17:49 [warn] 18177#0: *108064 an upstream response is buffered to a temporary file
/var/lib/nginx/tmp/fastcgi/9/86/0000000869 while reading upstream, client: 10.21.48.88,

However, 'client_max_bdy_size' is set at 128M in Nginx configuration file. I would say that is quite large.

Thanks for your response.

Hello, I really need urgent help.

I set up an automatic email responder in Roundcube, but something went very wrong: it started replying not only to new incoming messages, but also to very old emails, even from two years ago.

Now I have a huge sending queue with hundreds of outgoing replies. How can I stop or cancel this queue immediately?

Thank you very much for your support.
