[SOLVED] API key in Delivery Status Notification

[garnoux]

Hi,
Following this documentation, i've configured my spamhaus account in proxmox DNSBL.
So now i'm using DQS (Data Query Service) instead of public mirrors.
The request was changed from 2.0.0.127.zen.spamhaus.org to 2.0.0.127.<key>.zen.dq.spamhaus.net
I've set the API key in the PMG Options


It works perfectly, but my question is :
Is the API key appearing in Delivery Status Notification sent to client in case of reject by the DQS ?

2026-04-12T21:40:53.984636+02:00 pmg postfix/postscreen[471153]: NOQUEUE: reject: RCPT from [185.255.112.179]:36930: 550 5.7.1 Service unavailable; client [185.255.112.179] blocked using MYAPIKEY.zen.dq.spamhaus.net; from=<sender@domain1.tld>, to=<receiver@domain2.tld>, proto=ESMTP, helo=<smtp.domain1.tld>

Thank's

Yes, it will be sent to the sender of your spam.
You can avoid that, see https://www.postfix.org/postconf.5.html#postscreen_dnsbl_reply_map

You need to be aware that /etc/postfix/main.cf is generated by PMG.
For your change to be persistent, you have to work with the templates.
