Roundcube plugin for catch-all mailboxes — inboxes that receive mail at many different local-parts on a domain (e.g. anything@example.com).

What it does

Identity auto-create on reply — when you reply to a message that was delivered to foo@example.com, the plugin creates a matching Roundcube identity (if missing) and preselects it as the From: header so your reply goes out as foo@, not the base mailbox address.
Optional Forward Email integration — when an API key is set, the plugin additionally provisions per-alias SMTP credentials via the Forward Email API so each reply authenticates as its own alias.

For persistent login / autologin, see the companion plugin teh-hippo/roundcube-remember-me.

composer require teh-hippo/roundcube-catchall

Then add roundcube_catchall to the plugins array in your Roundcube config.

cd /path/to/roundcube/plugins
git clone https://github.com/teh-hippo/roundcube-catchall.git roundcube_catchall

Add roundcube_catchall to $config['plugins'] in config/config.inc.php.

Minimum (shared-credential mode):

$config['catchall_domain'] = 'example.com';
$config['catchall_identity_autocreate'] = true;

With Forward Email per-alias provisioning:

$config['catchall_fe_api_key_plain'] = '…';
$config['catchall_fe_auto_delete']   = false;

Users can also set per-user Forward Email preferences under Settings → Catch-all in the Roundcube UI.
