I think I found it. The source of my problem was the nginx configuration. I try to hardening nginx against CSP and X-XSS-Protection with this directive:
add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;
inside my /etc/nginx/modules/headers.conf
When I commented out this line RC is working fine.
My headers.conf file:

Quote# security headers

add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-XSS-Protection "1; mode=block" always;
add_header X-Content-Type-Options "nosniff" always;
add_header Referrer-Policy "no-referrer-when-downgrade" always;
# add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

# . files
location ~ /\.(?!well-known) {
    deny all;
}

How can I modify Content-Security-Policy to be more secure? Is it ok to add just unsafe-eval like this?

Quote# security headers

add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-XSS-Protection "1; mode=block" always;
add_header X-Content-Type-Options "nosniff" always;

# add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline' 'unsafe-eval'" always;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

Several weeks ago (as of 9/15/24), the text (contents) in the Subject line for every incoming message disappeared. This happened in all archived messages dating back 10 years in all folders as well

I know there are contents in Subject lines because the contents appear when I reply to a message. (Not to mention that all archived messages in folders had text in Subject lines when originally received.)

I've tried dragging and moving the Subject column as well as other columns (e.g., From, Date, Attachments) to see if I can restore the Subject lines' text, but I think this screwed things up even more. This is because data from the Date column started appearing in the Subject line and data from the Size column began appearing in the Flag column.

Here is a link to a screenshot of the current Displayed Messages page:

Is there a way to restore default configurations?

If I'm not stating the problem correctly, please ask for clarification.

Any help will be appreciated.

Thank you,

Marie

The "ipad/iphone" version has been corrected.

+ issue fixed on phone
+ other minor fixes
+ better display of text email (no scrollbar):

what filtering plugin are you using and what is the exact rule you have created?

i see you have already enabled `imap_debug`. That log is probably the first place to look for answer. You should see a `UID FETCH` request when you try and list messages.

BTW in your config file you have both "$config['enable_caching'] = false;" and "$config['enable_caching'] = true;" and `enable_caching` is not a Roundcube config option. If you are trying to enable IMAP caching then leave it disabled while you are investigating the listing issue.

I made a basic filter to move emails where the body contains the word "unsubscribe" into a specific imap folder. However it seems like the filter is missing over half the emails from newsletter which do contain the word "unsubscribe".

What's going on?

The "unsubscribe" text isn't an image and it doesn't appear to be some weird unicode that looks the same but is actually different characters.

Hi, unfortunately not, I tried also other combinations (existing mail / imap IP etc).

I just did a CSS fix for safari (it works properly on Ipad)

Can you tell me if it works well on a mac laptop : https://github.com/seb1k/Elastic2022/issues/10


Thanks !

Hi guys,
I have really weird problem with RC 1.6.8-1 on ArchLinux machine. I try to build mail server. Right now I have dovecot installed and configured correctly. My users are store in LDAP and I'm able to login - everything is ok. I can read my emails via Thinderbird without a problem.

When I log into my account via Roundcube, I don't see any emails even though RC shows me the correct folder size and number of emails.
My config.inc.php
