I need to push a message notification to external system when they receive new emails from their mailbox，so I used the push_notification_lua plugin.

My dovecot configuration file is as follows：

plugin {     ....     push_notification_driver = dlog     push_notification_driver2 = lua:file=/etc/dovecot/custom-lua/push-notification.lua     push_lua_url = http://localhost:10421/internal/dovecot/email-notification/receive }

protocol lda {     mail_plugins = $mail_plugins sieve last_login push_notification mail_lua push_notification_lua     .... }

============= I print the 'event' param's value log in function 'dovecot_lua_notify_event_message_new' in my lua script: function dovecot_lua_notify_event_message_new(ctx, event)   dovecot.i_info("lua-push: event=" .. cjson.encode(event)) end

However, when I send a mail with multiple recivers, the notification event info seems to work abnormally.

Sender: wangzx@hxtmailtest.avicnet.cn Receivers: zhaoqb@hxtmailtest.avicnet.cn , wangzx7110@hxtmailtest.avicnet.cn

I found the two event object's field 'to_address' and 'to_display_name' value are same in /var/log/dovecot/lda.log. Please help me confirm if this is a bug?

The log in /var/log/dovecot/lda.log like bellow:

2025-08-06T09:38:11.383536+08:00 hxtmailtest-server dovecot: lda(wangzx7110@hxtmailtest.avicnet.cn)<548522><EkAeFgOykmiqXggAfhwsfQ>: lua-push: event={"snippet":"test!!","date":1754444290,"keywords":{},"to_display_name":"Zhaoqb","uid":19,"subject":"test","from_display_name":"","to_address":"zhaoqb@hxtmailtest.avicnet.cn","tz":480,"mailbox":"INBOX","to":"Zhaoqb <zhaoqb@hxtmailtest.avicnet.cn>, Wangzx7110\n <wangzx7110@hxtmailtest.avicnet.cn>","from":"wangzx@hxtmailtest.avicnet.cn","message_id":"<6e3a1265476c8197372afb7a1ac5ebbb@hxtmailtest.avicnet.cn>","uid_validity":1752827738,"flags":{},"from_address":"wangzx@hxtmailtest.avicnet.cn","name":"MessageNew"}
