have you had a look at the thunderbird_labels plugin?

Hey all. I'm wondering if there's a way I can use flags in multiple colors on emails. Right now I only see the red when I click on it. If there isn't a way to do this, can it be considered for an update? Thanks!

Hey all. I'm new to Roundcube and I'm wondering how I can use/get flags in multiple colors on emails. Right now I only see the red when I click on it. Thanks!

Hi,

I've been trying to sync up my caldav account to my native apple calendar app but it wont connect.
I have tried using the configuration file that is sent by webmail, but also setting it up manually by using the server address and port number.

Neither worked.

Could anybody give specific guidance? The devices I'm setting up on is a MacbookPro 2023


Thanks in advance

Signing is not supported. https://github.com/mailvelope/mailvelope/issues/769

Hi all,

I am trying to setup my roundcube client to encrypt and sign emails automatically using my gpg keychain on my computer. I have installed the mailvelope plugin and set it to prefer my gnupg keychain. In roundcube, I have enabled api access to mailvelope for my domain. The state of the "Use Mailvelope main keyring" does not seem to change anything.

If I click the "Encrypt" button above my message, then the mailvelope editor becomes embedded and I can send an encypted email. However, If I do not have the public key for a recipient, I am unable to only sign my message via this method, which should be possible.

If I use the toggles on the right of my message, then when I click send, I get an error saying that there is no private key. I suspect this is because mailvelope shows my "Main keychain" as empty (which is being used by roundcube) and my "gnupg keychain" as preferred.

I suspect that I have misconfigured either roundcube, mailvelope or both, but not sure what I need to do to get this to work. Any advice would be greatly appreciated.

Cheers,
Daisy

Roundcube is open source webmail software it is not a service. Only your service provider can answer your question as only they know how/why they have configured it so please ask them.

does http://mail.dcaky.cn/ not have a delete button for mail??

Hi all,

I'm running into an issue where recurring event exceptions (single-instance overrides using RECURRENCE-ID) seem to get silently dropped by the CalDAV backend. I wanted to check here before filing a bug report — maybe I'm missing something, or maybe this is a known limitation.

Backend: RoundcubePlus//XCalendar//Sabre//VObject//4.5.6//EN

The issue

When I PUT an ICS containing a recurring master event (RRULE) plus a modified single occurrence (same UID, with RECURRENCE-ID), the server responds 204 No Content (success). But a subsequent GET on that same resource only returns the master event — the exception/override VEVENT is gone.

```
BEGIN:VCALENDAR
PRODID:-//Test//EN
VERSION:2.0
CALSCALE:GREGORIAN
BEGIN:VEVENT

DTSTAMP:20260714T144618Z

END:VEVENT
BEGIN:VEVENT

SEQUENCE:11
STATUS:CONFIRMED
SUMMARY:Exception - moved 30 min later
TRANSP:OPAQUE
UID:test-recur-exception-001
END:VEVENT
END:VCALENDAR
```

The GET response should contain two VEVENT blocks: the master (with RRULE) and the exception (with RECURRENCE-ID:20260609T140000Z and the updated time of 14:30–15:00).

But with my instance of roundcube, only the master VEVENT is returned. The exception is gone entirely — no error, no partial data, just missing.

1. Has anyone else run into this with RoundcubePlus's CalDAV backend?
2. Is there a server-side config option that needs to be enabled to support recurrence overrides?
3. Is this a known limitation of this sabre/vobject-based backend, or should I file this as a bug?
