Dears,
I support a web application tool for company clients where it's required to confirm their information on registration proccess by replying to confirmation email .
IP: 194.58.96.144
DNS: sales-puratos.ru
The web tool able to send mails to any public email services besides corporate domain *@puratos.com which is behind MessageLabs infrastructure.
Main reason always remains the same:
501 Connection rejected by policy [7.7] XXXXX, please visit www.messagelabs.com/support...
I've double checked follow:
- IP is not black listed on any SBL's and DNS as well.
- Symantec IP investigation tool shows NO negative reputation of mentioned IP
- I've also sent email with de list request to: investigation@review.symantec.com with reply:
- "....We will investigate and if necessary setup counter measures to make sure that it is not blocked again in the future. The reason for your IP being identified as a zombie is that Symantec received what appears to be spam email traffic from your IP into its Probe Network and performed a series of tests to determine if your IP address was a mail server. Upon failing this initial test, we performed additional analysis of the email traffic prior to listing the IP."
- Web app. don't act as open relay
Email still don't reach any recepient within @puratos.com domain
I'll be apreciate You to investigate my case and release domain\IP form black lists.
Regards,
