Hi! I read the exim4 manual on SPF [1] and tried the example on my Debian buster server (even tried 4.94 from buster-backports) but discovered that exim4 wasn't built with libspf2 support, and stumbled on this old bug report.
Is there today any reason exim4-daemon-heavy isn't built with libspf2 support? Could this be revisited? Thanks, /Simon [1] https://www.exim.org/exim-html-current/doc/html/spec_html/ch-dkim_spf_and_dmarc.html#SECSPF
