Hi,

I'd like to setup a POP3/IMAP client in 'primitive' J2ME environment (old sony phone)

the simple j2me app is asking for
Address
Local host
Inbox type POP3/IMAP
Inbox host
Username
Password
Inbox port
SMTP host
SMTP password

which of these are bare minimum for accessing a roundcube inbox?

thanks in advance.

story: I've used html gmail for many years on java web browser opera mini but this was phased couple years ago, so i config gmail to forward email to temp yandex inbox which still has html but annoyingly yandex opted to enforce QR code 2FA login app.

Code Select Expand

// Path to a local mime magic database file for PHPs finfo extension.
// Set to null if the default path should be used.
$config['mime_magic'] = null;


Thanks a ton, the roundcube config did point to a wrong file. Setting it to the default path as you suggested fixed things.

Thanks a lot, I'll look into that!

Sounds like there is a problem with your mime magic database file. I'm not sure on what options there are to fix that on FreeBSD but Roundcube does have config option to set a custom path to one if you need to:

$config['mime_magic'] = null;


Roundcube 1.7.4, php 8.3.33, FreeBSD 14.4

Roundcube is unable to attach files with certain extension to a mail (e. g. .png, .jpg, .svg). Other file extensions work just fine (e. g. .pdf, .docx, .xls).

Trying to upload a .svg file, for example, logs the following error. Errors for .png and .jpg look identical.

Any ideas what could be causing this?

Thank you, JohnDoh and SKaero - I understand that I have to consider cpanel to find an answer.
How can I set this topic to "Solved" or "Closed", or, will this be done by an Forum Admin?

Based on the path you gave to get to BoxTrapper "CP Webmail Home | BoxTrapper" that is most likely maintained by cPanel.

Roundcube is open source webmail client, cPanel uses Roundcube in there portal so you can view your email in the browser.

I see in Roundcube UI an informational text "cPanel". Could it be that BoxTrapper is handled by cPanel? And, if so. what is the relation between cPanel and Roundcube?

It looks like your provider BoxTrapper is using a plugin to add the functionality you are talking about to their installation of Roundcube. Please contact them for more information.

After Login to UI, I go to :
CP Webmail Home | BoxTrapper | Sperr-/Zulassungs-/Ignorierliste bearbeiten|Zulassungsliste bearbeiten
There, it is mentioned, that the entries use Perl RegEx.
