    Hello,

    Our client is unable to send mail to Symantec Messaging Gateway users. Any attempts to do so are greeted with the following error:

    554 5.7.1 You are not allowed to connect.

    We have previously attempted to request an investigation using the form located [http://ipremoval.sms.symantec.com/lookup/] but have not received any reply or notice for several days. Additionally, we have confirmed the server in question is not participating in any outbound spamming or malicious activity.

    Please assist in removing the blacklisting placed on [138.128.170.18] or providing additional information that may assist our team in resolving this issue.

    Thank you for your assistance.
