spam filtering is something likely done by your email provider. there is no spam filtering built into roundcube. functions like that are best done on the server side so you dont get different results in different clients. please contact your email provider for support.

Hello!
I have noticed an on-going issue for about a month now.

Some incoming emails end up in our spam folders even if the senders are trusted, have marked other emails of those senders as not spam or have received other emails in the past from them without issues. This happens on all of our Roundcube accounts.

As we did not change any of our settings, I was wondering if anyone can assist. Let me know if you need further information.

Thank you in advance

there is some. if you expand the search box at the top of the message list then you get some predefined time ranges to limit you search by. if you actually want to select messages then run your search and use the select function.

Hello,

Is there currently a capability to select emails by date range?

Thanks

Mark

You are right, I just use the "sun" icon in the left side panel.

But I understand that it is a good thing to have a toggle in the message panel itself, like in Thunderbird where I myself use the toggle once in awhile. It would also be good to have when viewing a message in a new window.

That is something I can look at.

Thanks for your answer. I was able to fix it by reinstalling the package and, maybe the more importand point, by recreating the database.

The plugin looks good. One thing I don't see is a way to switch to light / default mode in case there is a message that needs to be view in the original form.

I wrote a plug-in for RoundCubeMail 1.7 that patches dark-mode to work in the message viewer and the message editor.

I hope someone can use it as well as myself.

/etc/roundcube/debian-db.php is not the default location for the Roundcube config, and because the error has "(using password: NO)" indicates that it likely not reading the config file at all assuming that there is a database password.

My guess is that was a change made in the package from your distro and its no longer checking the custom config location.
