In which case I am going to bet the issue is your machine does not 
support avx2,  which the default build of rspamd apears to be enabling.

One easy way to check is to force a build from source, and see what that 
does. The build should then detect what the build machine, your machine, 
supports and thus disable what is causing the problem.

If that works, then please file a ticket at

https://trac.macports.org/wiki/Tickets

asking the maintainer or spamd to address the issue, by disabling the 
automatic CPU capabilities detection in the default builds.

cheers Chris
