rspamd binaries fail with illegal instruction 4:

[Chris Jones]

what does

sysctl -a | grep machdep.cpu.features

give on the machine with the issues ? Does it list AVX2 ?

rspamd was recently (by Steven Smith) given a bit of an overhaul, adding 
a few new deps and features, see the history of recent commits at

https://github.com/macports/macports-ports/commits/master/mail/rspamd/Portfile

it could be one of these is giving the problems, not the rspamd build 
itself. Try seeing if build one of the various deps from source helps.
