Email Security.cloud

Dear Symantec-Team,

We had an email server going live last week and some email are being rejected with the "501 Connection Rejected" error.

IP: 

178.16.56.48

178.16.56.49

188.94.249.252

Could you please delist them, were not on any RBL

Thank you.

Hi Mwcm,

I have checed the IP's and two are listed (178.16.56.48,178.16.56.49) for which I have also submitted de-listings for.

Please accept our apologies for the severe delay in responding

Hi I can now confirm that your IP's are now clear.

Kind regards

Dave Parker

Hi Dave,

thanks for your reply.

I've got 2 Questions:

1. Are those IP's listed again?

2. Who could we as an ISP check your cloud-Services if we were blocked?

Kind regards

Marcel Schmidt

Hi Marcel,

Those IP's are clear no re-listing as far as I can see. We do make use of the PBL Spamhaus block list as part of are service. We also do have many other internal systems that are not publicly visible. They're only visible to our customers. This forum would be the best option for non customers currently.

Kind regards

Dear Dave,

Thanks for the fast reply.

How could we become a customer, to see your "internal systems that are not publicly visible". It's important for us to see

if we are listed instantly.

Kind regards

Hi Marcel,

Our scanning service is made up of a multi-faceted layered approach to email scanning. Customers of the Symantec.cloud service gain access to implement all or some of these controls these include personal blocked IP/Domain/Email Address lists, Block lists and different methods of Anti Virus and Anti Spam scanning engines.

Access to these are only visible to full Email Security.cloud customers. If you wish to become an email security.cloud customer you will need to enquire via the sales channel here:
