Here is my exact configuration from /etc/guix/mail/smtpd.conf (so 
no Scheme strings, no escapement):

--8<---------------cut here---------------start------------->8---
filter out proc-exec \
 "/run/current-system/profile/libexec/opensmtpd/filter-dkimsign\
 -d tobias.gr -s 2018 -c relaxed/relaxed \
 -k /etc/guix/mail/dkimproxy.key" \
 user nobody group nogroup # must be able to read the -k(ey file)
--8<---------------cut here---------------end--------------->8---

Note how I'm quoting the entire command line: the ‘filter’ keyword 
is taking only 7 arguments.

By the way, I could've sworn I shared this with you on IRC 
recently.  No?

Must be trippin,
