Hello,
I have made available my filter-rspamd for testing:
https://github.com/poolpOrg/filter-rspamd
A port was done for OpenBSD, I'm waiting for okays but OpenBSD users will be
able to setup antispam with:
pkg_add rspamd filter-rspamd
and adding the filter bits to smtpd.conf:
filter "rspamd" proc-exec "/usr/local/bin/filter-rspamd"
listen on ... filter "rspamd"
I have been running with this filter for a while now, so have other people.
You need to be running OpenSMTPD from OpenBSD -current or from the Github
repository.
Please test and report !
