Roundcube is open source webmail software it is not a service. It connects to your IMAP server similar to how Outlook does. The error you describe sounds a bit strange but Roundcube has is not involved at all when you are using Outlook. I suggest you contact your email provider and tell them the exact error message you get. They might ask you for the IMAP connection details you are using to confirm they are correct as well.

Hello - how are you? I don't know if anyone can help, and please forgive me - I'm not particularly savvy when it comes to these things!

I am able to access my webmail via roundcube on my main PC via a browser, and also via Outlook on the same PC. However, using the same credentials I am unable to access my mail from any other device, phone - tablet - other PC, the login always fails. It fails when logging in via the roundcube login page OR trying to login via outlook or any other email client.

Is this a 'roundcube' issue or an I barking up the wrong tree?

Any advice appreciated.

Thanks in advance!

I've got an answer.. So please close this topic.
Thanks, Rob

We want to forward messages depending on the cc-address or the bcc-address instead of 'only'the to-address...

I still don't have an answer, but it must be some odd caching issue as you suggested @JohnDoe. When I revert back to version 1.7-beta2 and even version 1.6.10 I now get the same behavior. I'll keep investigating and report back here if I find a solution. If anyone has ideas to try, I'm all ears. fwiw, I'm running a fedora 43 server with caddy v. 2.10.2.

Thanks for the reply.

No error messages in the roundcube errors.log file, and I am not using any imap or message caching:

// config/default.inc.php
$config['imap_cache'] = null;
$config['messages_cache'] = false;

Just in case, I rebooted the entire server and the issue persists.

The issue is with LemonLDAP-NG, not with roundcube.

There is an issue with the nginx-lua-headers.conf, it messes with the cookie.

Hi,

Sorry if this goes a bit outside pure email topics, but the logic feels close to how identities are handled here.

I recently looked into how animal RFID microchips work. The chip itself only stores a unique ID and all real information lives in an external database that gets queried when the chip is scanned. It reminded me of how Roundcube acts more like an interface while IMAP remains the actual data source.

I'm wondering if anyone ever used Roundcube as a lightweight interface to consult external identifiers stored somewhere else, not emails but things like inventory IDs or badge references tied to another system.

I'm not sure if this would make sense from a security or performance perspective, so I'm curious if any admins experimented with something similar or maybe rejected the idea for good reasons.

Thanks.

is there anything in the roundcube error log? also do you have any of the imap or message caching options enabled? if so does resetting the cache make any difference?

Hey everyone,

I'm trying to send an eSIM promo code to a colleague using Roundcube, but the link always ends up unreadable or the formatting gets messed up. I've tried plain text and HTML, but it still fails.
Has anyone managed to handle external links in emails without Roundcube altering them? I really need the code to stay clickable and clear.
