Thanks. I subimitted

Hi,

I sent to investigation@review.symantec.com but I have not received any response yet.

My client is furious because his messages do not reach the destination, which are his clients.

thanks.

Hi Bruno

I was able to look into the IP range you provided and can see that the majoirty of the IPs in the range had been throttled to a point where we would reject connections from them. This is most likley due to the previous owners of the IPs being compromised or relaying spammy content.

I've now removed the throttling that's in place on these so if you test you should not see any further issues with this.

Kind regards
