Cloudron Forum

@nebulon , thanks for reply.
in the first post, I copied a undeliverable testmail from spamhoaus to cloudron, b/c it was denieing the reception.

here a little oversight:

and they all look similar…

all these hosts are N.O.T. blacklisted. I checked.
also, false positives…

@gerard thanks for testing. A fix for this is coming next release.

The issue is fairly recent. SpamHaus made some policy change when requests come from IPv6 addresses.

Good suggestion. For future reference:

The current zen spamhaus check only covers SBL, SBLCSS, XBL and PBL blocklists. To query DBL, one can do host domain.com.dbl.spamhaus.org 127.0.0.1 on cloudron . Would be good to get this automated like the zen check
