Hi,
I'm running several UTMs as hardware appliances, but I also do run one UTM Home Edition installation for my personal use.
Somehow I do have a problem integrating zen.spamhaus.org, When I add it do the DNSBLs for some reason mails don't get blocked by it and I don't understand why.
Any other DNSBL I add does work, zen.spamhaus.org not.
Does Sophos somehow prevent the use of it?
Is there any log I can check if it does query Spamhaus for data?
I received a new IP by my provider and still it doesn't work. At first I thought maybe Spamhaus blocked me, but their usage terms are pretty clear:
1) Your use of the Spamhaus DNSBLs is non-commercial*,
and
2) Your email traffic is less than 100,000 SMTP connections
per day, and
3) Your DNSBL query volume is less than 300,000 queries
per day.
so I should be more than ok...
Thank you.
