AVG false positive spam detection

Hello Frank.
I am sorry to hear about the inconvenience caused. Could you please let me know whether it is a free or a paid version of AVG you are using?

AVG is detected email from my domains as spam. Not in any RBLs and I enforce a zero tolerance spam policy.

Who can I contact to help me resolve this?

I'm using AVG IS 2015 (paid)

First, I want to say, thanks for the feedback. It turns out that my IP address was hidden in an RBL that I am unable to scan to see if it's listed. The RBL is cloudmark; I think it ought to be criminal for them to list IPs that causes email to be marked as spam but one cannot readily look at their database of IPs.
Now that I'm delisted (even though I never could see my IP address in their RBL) I hope my emails won't be marked as spam - time will tell. AVG should refrain from using such cloudmark (I can't bring myself to capatilize their name).

Frank,
you can reduce AVG SPAM SCORE. By default it is set to 90 which least aggressive. If you set it to a value 0 almost all emails will be marked spam. You can reduce it to a value like 50 or 60 or value according to your wish for better spam filter.

Open AVG user interface>click options>advanced settings>on the left pane select Email Protection and expand it by clicking [+] sign>select Anti Spam and expand it>click settings>on the right pane under Anti-Spam settings move the slider according to your wish to provide better results>click apply and OK.
Thank you.
