Hi. Whenever I try to reply to an email, or send one out, a message appears that says:

Failed to add recipient "[email protected]" (Domain searts.org has an outgoing mail suspension. Message discarded.).

How can I find out what's causing the problem so I can fix it? There's no "Help" button in Roundcube.

Thanks for any advice.

Clare Higgins

okay thank you I might need to go to apple, cause I've had no success adding it to my Mac mail .

Roundcube is opensource webmail software, not a service. Your provider is using it to give you web based access only. Your provider hosts your mailbox. If you know the IMAP details then you can use any IMAP client to access your mailbox. Then you could download your messages and transfer them to your new provider.

1.4.15 was the last release of version 1.4, which is now end of life. See here.

New to the board.
I have a website hosted by a provider and unfortunately they are not answering my emails.
So I'm thinking of changing my website provider but is there any way I can still access my round cube hosted emails.  I have the password but I'm trying to log in and I get this error.

Does anyone have any suggestions as to how I can access my emails or are they lost

Any help would be appreciated.
I am not completely computer illiterate but I'm not super savvy either. 
Thank you so much for any assistance .

My fix is putting these lines in dovecot.conf

mail_home = /home/%{user}
mail_driver = mbox ← changed this from maildir
mail_path = ~/mail
mail_inbox_path = /var/mail/%{user} ← added this

And adding the 'user' to the 'mail' group.

Hi,

On my LAN Dovecot, Postfix on the one server work fine. Also Thunderbird works fine as an e-mail client.

Now I want to use RC also (on the same server).
So I installed RC and nginx.
My browser shows the login page.

But I can't login
(stream_socket_client(): Failed to enable crypto
Unable to set local cert chain file `/etc/dovecot/private/xxxx.cert'; Check that your cafile/capath settings include details of your certificate and its issuer).

What are the correct RC settings for IMAP/SMTP when using self-signed certificates?
Below is my current configuration.

-----------------------------------------------
Dovecot/Postfix/Thunderbird: OK
Thunderbird: SSL/TLS, Normal password, server: imap.domain.lan:993

Roundcube:
// --------------- IMAP ---------------------------------------

$config['imap_host'] = 'ssl://imap.domain.lan:993';
$config['imap_conn_options'] = [
  'ssl'        => [
    'verify_peer'  => true,
    'verify_peer_name'  => true,
    'verify_depth' => 3,
    'local_cert'  => '/etc/dovecot/ssl/xxxx.cert',
    'local_pk'    => '/etc/dovecot/ssl/xxxx.key',
    'allow_self_signed' => true
  ],
];
$config['imap_auth_type'] = 'PLAIN';

// --------------- SMTP ---------------------------------------

$config['smtp_host'] = 'ssl://smtp.domain.lan:587';
$config['smtp_conn_options'] = [
  'ssl'        => [
    'verify_peer'  => true,
    'verify_peer_name'  => true,

  ],
];

Hi SKaero
After enabling logging in Dovecot I can see the path to the ~/mail/ folder is correct.  I can see a 'permission denied'.  Is it saying no permission to access ~/mail/ folder?  This is what I have.  I seams it is saying these rights are not correct.  If that is true what should they be?  Obviously things have changed (not my machine though).  All worked before upgrade to Fedora 43

I can see from the IMAP log that Roundcube is working correctly, its asking for messages in the inbox "C: A0003 STATUS INBOX (MESSAGES UNSEEN)" and then Dovecot says there are no messages "S: * STATUS INBOX (MESSAGES 0 UNSEEN 0)"

This is most likely a configuration or maybe a permissions issue with Dovecot. You'd need to dig further into the Dovecot logs and configs to confirm.

Thank you for your reply.

This is from the imap log.  I do not see anything out of ordinary.  I noticed it references Dovecot.  Dovecot is a fresh install.  I have not done any configuration.  It's config is after imap log.
