551 issue - my server has been blocked by the McAfee global block list

Hi

I am unable to send out email to specific client.

The emails are returned as a 551 issue - its states that my IP is blocked by McAfee global block list.

Please advise what I should do.

I have screened by IP with McAfee trusted sources, and my IP address is clean and its without any risk or threat.

My IP is not listed in spamhouse either in any of the categories.

Please advise

Moved provisionally to Siteadvisor Enterprise as hopefully a better spot to get attention.

how do you know that it is blocked by Trusted resource or GTI? any screen shot would be helpful to know the root cause.

hi

the way know it is blocked, is from the return email from the client's server indicating so....indicating the 551 issue.

i have tested my ip with trusted source, and there is no reading of low reputation
