Wietse: > Did you build Postfix or OpenDKIM yourself?
I installed them with the xbps package manager on Void Linux (x86_64-musl). Postfix: https://github.com/void-linux/void-packages/tree/master/srcpkgs/postfix OpenDKIM: https://github.com/void-linux/void-packages/tree/master/srcpkgs/opendkim Bill & L.P.H: Oh I'm definitely following an old guide: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy (2014). My main.cf now reads: > milter_protocol = 6 But the issue still persists. If I remove this directive altogether the issue also still occurs. Andrey & Viktor: My configuration now reads: > smtpd_milters = inet:[127.0.0.1]:12301 > non_smtpd_milters = inet:[127.0.0.1]:12301 The warning still shows up, just with a new address: > postfix/cleanup[20180]: warning: milter inet:[127.0.0.1]:12301: can't read > SMFIC_EOH reply packet header: Invalid argument Thanks all for the debugging help so far.
