Abuse Message [AbuseID:C0F5DA:1F]: Microsoft Spam

It has come to our attention that the IP address of a server you have with us is sending emails to Microsoft spamtraps.

These emails are being sent from the following IP:

We are sending you this email for your information. You do not need to respond, but we do expect you to check the server and to resolve this issue.

If legitimate emails are being sent, then please make sure you clean up the database of recipient email addresses, as they were clearly not acquired using confirmed opt-in (COI). Please also make sure that there is an easy method to opt-out (unsubscribe), check that you have a valid PTR record for the IP, and consider setting up SPF and DKIM, if not already configured.

If spam is being sent, please resolve this as soon as possible. It is important that the underlying issue that caused the spam to be sent gets fixed. Possible causes include hacked email accounts, malware infections, open proxies, malicious CMS addons/plugins, or more. Please secure the server and take steps to make sure this doesn’t happen again. If the server shouldn’t send any emails, consider removing any mail server software and/or blocking the appropriate ports.

Please note again that this is a notification email only, you do not need to respond. However, we do expect you to resolve the issue. If we continue seeing reports of spam from your IP address, then we will contact you again.
