I have a business email address, which appears to be blocked by Trendmicro and just after some advice.
There's a link in the bounce back email https://ers.trendmicro.com/reputations/index?ip_address=18.104.22.168 and it says this IP is on a blacklist.
I'm guessing my client uses Trendmicro, so he can't accept my emails.
Now as far as I know, I have never spammed anyone.
I get this message when I send from home (Virgin media), or from the studio (which is in a shared office).
I can't remove the IP from the banned list.
Does anyone know what I should do?
