Hi,
if i set an “always_bcc” entry in postfix extra.conf, then mailcow sends me every minutes empty mails like that:
Return-Path: <watchdog@invalid>
Delivered-To: mailarchiv@[meine domain]
Received: from [meine domain] ([172.22.1.253])
by 910b9480ae0b with LMTP
id 0AbdMrlsiGS/KQAArYk5hw
(envelope-from <watchdog@invalid>)
for <mailarchiv@[meine domain]>; Tue, 13 Jun 2023 15:18:49 +0200
Received: from 1e4907408845 (mailcowdockerized-watchdog-mailcow-1.mailcowdockerized_mailcow-network [172.22.1.2])
by mg.repcom.de (Postcow) with SMTP id C8C665A3F13
for <watchdog@localhost>; Tue, 13 Jun 2023 15:18:49 +0200 (CEST)
Where can i stop this?
