Hi there,
I upgraded a customer to Mail Security 6.3 last week and since then lots of legit emails are being detected as spam.
What I've noticed in the logs is the entry "URL (domain.com) found on cloud blacklist", with domain.com being the customers own domain name, and it's affecting reply emails, so Eset is picking the domain name out of the email signature I'm guessing.
The thing is I cannot find what blacklist this domain is on and I am not convinced it is one. I spoke to Eset support and he couldn't find it any blacklists and also couldn't tell me what the 'cloud blacklist' is,
I've added the domain to 'Ignored Body Domain list' which has made no difference. I'm not using any RBL or DNSBL servers.
Can anyone offer any help or advice?
Thanks.
