Howdy,

I've noticed that some of my email, coming from an internal spam filter is being marked as spam:

Aug 24 21:13:05 d-11-1 synchronet: mail 0082 SMTP DNSBL Query: 9.5.7.9.9.d.e.f.f.f.9.2.c.0.2.0.4.9.4.2.4.1.3.0.0.0.4.3.6.0.4.2.sbl.spamhaus.org resolved to: 127.255.255.254

Aug 24 21:13:06 d-11-1 synchronet: mail 0082 SMTPS [2406:3400:314:2494:20c:29ff:fed9:9759] Receiving mail message from <bt.wubhkdac30=ezymsq56sigp=eh3dkymm2l@em427968.dlcm.co> to <deon.george@bbs.leenooks.net>

According to spamhaus, 127.255.255.254 is not a confirmation of SPAM (https://www.spamhaus.org/news/article/807/using-our-public-mirrors-check-your-return-codes-now.) , but rather an indication that the system querying its services do not provide a rDNS. So is there a way to not mark this as spam?

I tried to update the spamblock_exempt.cfg with the relays IPv6 address (..:9759), but it doesnt seem to make a difference. Does this accept IPv6 addresses?

On a related topic, I tried to enable email forwarding to another email that I read more often, but mail never made it.

I assuming the forwarding failed, because the email wasnt actually from bt.e2013...@...dlcm.co, it was from <REDACTED>

Anyway to fix that?
